Subject: [PATCH v7 0/2] Input: cros_ec_keyb - add function key support

Changes from v6:
  - Fixed a bug where normal key were sending the wrong MSC scancode
  - Added setkeycode handling so fn functionality is recomputed in
    runtime when the keymap is changed

Changes from v5:
  - minor renames/cosmetic changes
  - dropped the *_key_status array, tracking using the idev->key bitmask

Changes from v4:
  - just a comment tweak

Changes from v3:
  - implemented fn layer runtime detection
  - tweaked cros_ec_keyb_fn_code to return back the correct position
    code

Changes from v2:
  - renamed the dt property to use-fn-map, dropped the example
  - added few function comments
  - added a helper for obtaining the fn code
  - reordered, dt patch first

Changes from v1:
  - change struct to short types
  - refactored the fn key handling in its own function
  - changed props to use the google, prefix
  - reworked the properties to use an overlay map rather than a
    dedicated one
