Use the EC_CMD_GET_FEATURES message to check the supported features for
each MCU.

Add the core functions to be able to support the sensors attached behind
the ChromeOS Embedded Controller and used by other IIO cros-ec sensor
drivers.
The cros_ec_sensor_core driver matches with current driver in ChromeOS
4.4 tree, so it includes all the fixes at the moment. The support for
this driver was made by Gwendal Grignou. The original patch and all the
fixes has been squashed and rebased on top of mainline.

Newer revisions of the ChromeOS EC add more events besides the keyboard
ones. So handle interrupts in the MFD driver and let consumers register
for notifications for the events they might care.
To keep backward compatibility, if the EC doesn't support MKBP event, we
fall back to the old MKBP key matrix host command.

The EC_CMD_PWM_{GET,SET}_DUTY commands allow us to control a PWM that is
attached to the EC, rather than the main host SoC. The API provides
functionality-based (e.g., keyboard light, backlight) or index-based
addressing of the PWM(s). Duty cycles are represented by a 16-bit value,
where 0 maps to 0% duty cycle and U16_MAX maps to 100%. The period
cannot be controlled.
This command set is more generic than, e.g.,
EC_CMD_PWM_{GET,SET}_KEYBOARD_BACKLIGHT and could possibly used to
replace it on future products.
Let's update the command header to include the definitions.

Update cros_ec_commands.h to the latest version in the EC
firmware sources and add power domain and passthru commands.
Also, update lightbar to use new command names.

In <https://lkml.org/lkml/2014/6/10/265> pointed out that the 10-bit
flag in the cros_ec_tunnel was useless. It went into a 16-bit flags
field but was defined at (1 << 16).
Since we have no 10-bit i2c devices on the other side of the tunnel on
any known devices this was never a problem. Until we do it makes
sense to remove this code. On the EC side the code to handle this
flag was removed in <https://chromium-review.googlesource.com/204162>.

This just updates include/linux/mfd/cros_ec_commands.h to match the
latest EC version (which is the One True Source for such things). See

This file is included verbatim from the ChromeOS EC respository.
Ideally we would prefer to avoid changing it, to make it easier
to track this rapidly-changing file.
