Instead of enabling power button SMI unconditionally, add a boot state
handler to enable power button SMI just before jumping to
payload. This ensures that:
1. We do not respond to power button SMI until we know that coreboot
is done.
2. On resume, there is no need to enable power button SMI. This avoids
any power button presses during resume path from triggering a
shutdown.

Do not use the global platform_i2c_transfer() function that can only be
implemented by a single driver. Instead, make a `struct device` aware
transfer() function the only interface function for I2C controller dri-
vers to implement.
To not force the slave device drivers to be implemented either above
generic I2C or specialized SMBus operations, we support SMBus control-
lers in the slave device interface too.
We start with four simple slave functions: i2c_readb(), i2c_writeb(),
i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec-
tive SMBus functions. But we keep aliases because it would be weird to
force e.g. an I2C EEPROM driver to call smbus_read_byte().

Split `i2c.h` into three pieces to ease reuse of the generic defi-

* `i2c.h` - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
per board, devicetree independent I2C interface
* `i2c_bus.h` - will become the devicetree compatible interface for
native I2C (e.g. non-SMBus) controllers

Tested to ensure that a default build without CONFIG_CHROMEOS has this

ensured that when this option is disabled (for Chrome OS) then flashrom
can be used with the --wp-enable and --wp-disable commands, depending

We were explicitly passing CC and TARGET_CC to configure but overwrote
that decision later by passing CC (with the value of TARGET_CC) directly
to a recursive make call. The latter overwrite was introduced because
`unexport` alone doesn't work on variables that were specified on a make
command line (they are added to MAKEOVERRIDES and passed to further re-
cursive make calls).
Instead of unexporting random variables, unexport those that were actu-
ally passed from payloads/external/Makefile.inc and clear MAKEOVERRIDES.
Do not pass OBJDUMP as that is nowhere to be found in the GRUB sources.
And, last but not least, add --disable-werror because building GRUB is

The PMIO region was moved, but not updated in the ASL. Change to
generate \_PR table runtime and to report the correct PMIO region
and length.
Fix on Kahlee, where the EC overlaps the region:
[ 0.802721] cros_ec_lpcs GOOG0004:00: couldn't reserve region0
[ 0.807446] cros_ec_lpcs: probe of GOOG0004:00 failed with error -16
BUG=b:63902389
BRANCH=none
TEST=Cros_ec_lps can reserve the region. ACPI tables are correct.

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`.
