Subject: [PATCH 8/9] HID: apple: Add support for MacBookAir9,1
 keyboard/trackpad

This commit adds the necessary IDs and configuration for the MacBook Air
(Retina, 13-inch, 2020) [MacBookAir9,1 J230K iBridge2,15]

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