This patch adds a few retries to NVRAM read/write transactions with the
EC. Failing to read the NVRAM is not fatal to the boot, but it's still
pretty bad... especially since a single initial read failure will cause
vboot to blindly reinitialize the whole NVRAM with zeroes, destroying
important configuration bits like dev_boot_usb. The current EC
transaction timeout is one second, so the three retries added here can
potentially increase boot time by three seconds per transaction... but
this shouldn't happen in any normal case anyway, and if there are errors
a little extra wait is probably preferrable to nuking your NVRAM.
(Also, added a missing newline to an error message in the EC code.)

The EC behavior for reading events from the ACPI interface was broken
with this commit:
d899fda lpc: ACPI query-next-event drops masked events
https://chromium-review.googlesource.com/194935
This is causing no EC wake events to be logged. To make sure they are
logged once again set the wake mask before querying for events.
Also remove the check for port80 event logging since this is no longer

The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.
Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.
The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

The SPI drivers for tegra and exynos5420 have code in them which waits for a
frame header and leaves filler data out. The SPI driver shouldn't have support
for frame headers directly. If a device uses them, it should support them
itself. That makes the SPI drivers simpler and easier to write.
When moving the frame handling logic into the EC support code, EC communication
continued to work on tegra but no longer worked on exynos5420. That suggested
the SPI driver on the 5420 wasn't working correctly, so I replaced that with
the implementation in depthcharge. Unfortunately that implementation doesn't
support waiting for a frame header for the EC, so these changes are combined
into one.

Whenever spi_xfer is called and whenver it's implemented, the natural unit for
the amount of data being transfered is bytes. The API expected things to be
expressed in bits, however, which led to a lot of multiplying and dividing by
eight, and checkes to make sure things were multiples of eight. All of that
can now be removed.

Comment #endif /* FOO */ pairings.
Alphabetise headers and remove any #if CONFIG_ guards around them.
Background rational:
Remove guarding the inclusion of headers based on CONFIG_ options. This
*potentially* could hide issues such as functions being swapped from
under our feet, since different runtime behaviour could be declared with
the same function same name and type-signature. Hence, depending on the
header we happen to get may change runtime behaviour.

Before /proc/ioports shows:

0804-08ff
We'd like just a single 256-byte region at 0x800, but ASL can't handle that.
So this will work:
