[PATCH] platform: chrome: Add input dependency for tablet switch driver

[Arnd Bergmann]

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!
ERROR: "input_register_device" [drivers/platform/chrome/chromeos_tbmc.ko] 
undefined!
ERROR: "input_set_capability" [drivers/platform/chrome/chromeos_tbmc.ko] 
undefined!
ERROR: "devm_input_allocate_device" [drivers/platform/chrome/chromeos_tbmc.ko] 
undefined!

This adds the corresponding Kconfig dependency
