Input: mt6779-keypad - support double keys matrix
MediaTek keypad has 2 modes of detecting key events:
- single key: each (row, column) can detect one key
- double key: each (row, column) is a group of 2 keys
Double key support exists to minimize cost, since it reduces the number
of pins required for physical keys.
Double key is configured by setting BIT(0) of the KP_SEL register.
Enable double key matrix support based on the mediatek,keys-per-group
device tree property.
