To reduce code and improve performance of the embedded controller
firmware, pragma __aligned(2) or __aligned(4) are used when alignment to
16 or 32 bit boundary is expected.
Define all ec_align to packed when compiling kernel.

Update the feature enum for the Chromebook Embedded Controller to the
latest version. Some of these enums are still not used in the kernel but
we might be also interested on have these enums up to date. Userspace
can use them to query the features to the EC via the cros-ec character
device.
While here, also fix a typo in one comment in the enum.

Introduce the command and response structures for the second revision
of the host sleep event. These structures are part of a new EC change
that enables detection of failure to enter S0ix. The EC waits a
kernel-specified timeout (or a default amount of time) for the S0_SLP
pin to change, and wakes the system if that change does not occur in
time.

A new more command has been added to the ChromeOS embedded controller
that allows to get the number of charger port count. Unlike
EC_CMD_USB_PD_PORTS, this new command also includes the dedicated
port if present.
This command will be used to expose the dedicated charger port
in the ChromeOS charger driver.

cros_ec_commands.h, has been modified several times and it has grown a
lot, unfortunately, we didn't have care too much about the documentation.

Immutable branch (mfd, chrome) due for the v4.19 window
Immutable Branch which moves the cros_ec_i2c and cros_ec_spi
transport drivers from mfd to platform/chrome. Changes in arm are a simple
rename in defconfigs. Change in input is a rename in help text.
The USBPD charger driver gets information from the ChromeOS EC, this
patch adds the USBPD charger definitions needed by this driver.

This is the driver for the USB Type C cable detection mechanism
built into the ChromeOS Embedded Controller on systems that
have USB Type-C ports.
At present, this allows for the presence of display out, but in
future, it may also be used to notify host and device type cables
and the presence of power.
