Hi Ryan,

Thank you for the patch.

MT8173's keypad controller is the same block this driver already handles.
Its register map agrees offset for offset with the MT6779 one -- STA 0x00,
MEM1..MEM5 0x04..0x14, DEBOUNCE 0x18, SEL 0x20, EN 0x24 -- and
mt6779-keypad drives it with no code change, so the node only needs the
fallback compatible in second position. Add the mt8173 string to the
existing enum, which is what mt6873, mt8183, mt8365 and mt8516 already do.

Verified on an MT8173 board (Amazon Fire HD 10 2017): the volume rocker
reports through mt6779-keypad with no driver modification.
