Earlier the EC expected the host to set appropriate masks before
reading host events. However, with recent change in EC, this is no
longer required. This change removes the setting of wake_mask before
and after reading the host events. However, in order to support older
versions of EC, a new feature flag is added on the EC side that
informs the host whether or not it is using the new way of reporting
host events without having to set wake mask.
CQ-DEPEND=CL:719578
TEST=Verified that EC wake events are correctly logged with both old
and new versions of EC.

EC maintains a FIFO of all MKBP events and sets host event whenever
a new entry is added to the FIFO. Clearing only the host event for
MKBP creates an inconsistent state where there are pending MKBP events
in the FIFO but host event for MKBP is cleared. In order to maintain a
consistent view, host should clear all MKBP events in the FIFO if host
event is being cleared.
This change drains out all the MKBP events in the FIFO when
clear_pending_events is called.
TEST=Verified by adding debug logs in EC to verify that all the MKBP
events that occur before clear_pending_events is called get cleared
from the FIFO.

This patch removes checks that ensure EC to be in RO for recovery
boot. We do not need these checks because when recovery is requested
automatically (as opposed to manually), we show 'broken' screen where
users can only reboot the device or request recovery manually.
If recovery is requested, Depthcharge will check whether EC is in RO
or not and recovery switch was pressed or not. If it's a legitimate
manual recovery, EC should be in RO. Thus, we can trust the recovery
button state it reports.
This patch removes all calls to google_chromeec_check_ec_image,
which is called to avoid duplicate memory training when recovery
is requested but EC is in RW.

Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.
Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.
The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.
Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.
Patched with Coccinelle using the clumsy spatch below and some manual
changes:
* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.

ToString() requires the input buffer data to be null-terminated,
but the data returned by the EC is not, leading Windows to fail
to report any battery data at all. Correct this by concatenating
a null terminator (0x00) to the end of the buffer data before
inputting to ToString() where needed
TEST: boot Windows on google/butterfly, observe battery data
reported correctly.

The IO region defined for EC_HOST_CMD_REGION1 was incorrectly
using EC_HOST_CMD_REGION0 for the range maximum so the region
was showing a minimum of 0x880 and a maximum of 0x800.
Both min and max should report the same value as this region
is fixed and cannot be relocated by the OS.

The thinkpad-acpi driver uses the UCMS (CMOS) ACPI method to control the
ThinkLight from the Operating System. This patch adds partial support for
that method, enough to enable or disable the ThinkLight:
echo on >/proc/acpi/ibm/light
echo off >/proc/acpi/ibm/light
With the original BIOS the UCMS method exposes a wide range of values
through a generic /proc/acpi/ibm/cmos interface. With the changes suggested
in this patch that interface is also exposed but only accepts the commands
to enable or disable the ThinkLight; all other commands are ignored.
This change would potentially benefit all currently supported Thinkpad
models, I only have an X201 available for tests though.

This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

The Lenovo H8 battery interface uses a paged EC memory area.
Some Thinkpads (in particular the S230U) use a different EC controller
(ENE KB9012) with mostly compatible firmware, which requires an explicit
delay between writing the page register and reading the page data.

Currently, when using `iasl` 20140926-32 [Oct 1 2014] from Debian 8
(Jessie/stable), the build of the Lenovo X60 fails due to syntax errors.
ASL 2.0 supports `<<`. For consistency, right now, coreboot still uses
the old syntax. So use `ShiftLeft` instead, which also fixes the build
issue with older ASL compilers.

thinkpad_acpi expects a SSMS method to turn on/off the mute LED
and a MMTS method to turn on/off the microphone mute LED. With
these methods implemented the driver can correctly sync the LEDs
with the corresponding statuses.
There seems to be two different bits to mute the audio in the
Lenovo H8 EC:
* AMUT, used internally (for example to disable the audio before
entering S3).
* ALMT, controllable by the OS, which also toggles the mute LED
(if present).
Tested on a X220T and on a X201.
