Subject: [PATCH 6/9] HID: apple: Add support for MacBookPro16,2
 keyboard/trackpad

This commit adds the necessary IDs and configuration for the MacBook Pro
(13-inch, 2020, Four Thunderbolt 3 ports) [MacBookPro16,2 J214K
iBridge2,16]

This model uses the APPLE_BACKLIGHT_CTL quirk to expose keyboard
backlight controls.
