[PATCH 0/3][X/Y/Z] Add hotkey supports for new Thinkpad systems

[Alex Hung]

Impact:
  New Thinkpad systems comes with new ACPI ID and/or new BIOS events, and 
  thinkpad_acpi requires to handle them differently.

Fix:
  The fixes include 1) add a new ACPI ID, 2) add new keycodes for hotkeys.

  The patches are included in upstream and are cherry-picked from Linus's repo.

Regression Potential:
  The impacts should be low as the fixes affect either systems with new ID or
  with the new BIOS events.

Note:
  Patch "platform/x86: thinkpad_acpi: Adding new hotkey ID for Lenovo thinkpad"
  is not needed for Zesty
