Input: mt6779-keypad - fix hw code logic and row/col selection

This serie is the first follow-up on the mt6779-keypad in
order to enable it on the MediaTek mt8183-pumpkin board.

To fully enable it on mt8183-pumpkin, we still need:
* double key support
* dts changes

To ease up reviewing, I preferred sending this first.

The first patch fixes a logic bug based on the (non-public) datasheet
I have.
The second patch configures the keypad correctly in order to not
report bogus values.

Thank you,
Mattijs

Changes in v3:
* reworked row/column logic as discussed in [1]
* Dropped Angelo's review since patch 1 changed

Changes in v2:
* Simplified SEL_COL/ROW_MASK macros as suggested by Dmitry
* Added Angelo's Reviewed-by on patch 1
