Pull chrome platform updates from Benson Leung:

 - further changes from Dmitry related to the removal of platform data
   from atmel_mxt_ts and chromeos_laptop.

   This time, we have some changes that teach chromeos_laptop how to
   supply acpi properties for some input devices so that the peripheral
   driver doesn't have to do dmi matching on some Chromebook platforms.

 - new Chromebook Tablet switch driver, which is useful for x86
   convertible Chromebooks.

 - other misc cleanup

* tag 'chrome-platform-for-linus-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/bleung/chrome-platform:
  platform/chrome: Use to_cros_ec_dev more broadly
  platform/chrome: chromeos_laptop: fix touchpad button mapping on Celes
  platform: chrome: Add input dependency for tablet switch driver
  platform/chrome: chromeos_laptop - supply properties for ACPI devices
  platform/chrome: chromeos_tbmc - add SPDX identifier
  platform: chrome: Add Tablet Switch ACPI driver
  platform/chrome: cros_ec_lpc: do not try DMI match when ACPI device found

Move to_cros_ec_dev macro to cros_ec.h and use it when the private ec
object is needed from device object.

Celes has newer touch controller (compared to the controllers used in
older BayTrail-based devices) and so uses the same button mapping as
Samus.

This fixes the issue with mouse button being stuck in pressed state
after the first click.

Without CONFIG_INPUT, or with a modular input layer and built-in
tablet driver, we get a link error:

ERROR: "input_event" [drivers/platform/chrome/chromeos_tbmc.ko] undefined!

This adds the corresponding Kconfig dependency

BayTrail-based and newer Chromebooks describe their peripherals in ACPI;
unfortunately their description is not complete, and peripherals
drivers, such as driver for Atmel Touch controllers, has to resort to
DMI-matching to configure the peripherals properly. To avoid polluting
peripheral driver code, let's teach chromeos_laptop driver to supply
missing data via generic device properties.

Note we supply "compatible" string for Atmel peripherals not because it is
needed for matching devices and driver (matching is still done on ACPI HID
entries), but because peripherals driver will be using presence of
"compatible" property to determine if device properties have been attached
to the device, and fail to bind if they are absent.
