- catchup in the 'ifm AC14xx' board's device tree with recently added
keypad-matrix driver features: individual pin polarity for rows and
columns, push/pull pin operation for columns
- slight re-ordering of keypad-matrix related settings, and tuning of
timing specs for more reliable detection of short lived key presses
(including a range spec to reduce timer management overhead) as well
as a slightly increased overall matrix poll frequency
- fix keymap comments, make the names match the codes
