Features not supported yet:
 - Panel Backlight
 - Lid Detection
 - Battery
 - EFI Variable Access
 - Cameras

1. Panel backlight, lid detection and battery will be supported with the
   EC driver upstreamed.
2. EFI variables can only be read with the QSEECOM driver, and will be
   enabled when the driver is fixed.
3. Cameras are tested to work with modified downstream driver, and once
   drivers for these camera modules are included in the tree, cameras can
   be enabled.

Features won't be supported:
 - External Display
 - Fingerprint

1. To make external display work, more reverse engineering may be required,
   but it's beyond my ability.
2. Fingerprint is controlled by TrustZone, meaning direct access to it
   isn't possible.
