twl4030-gpio: cleanup debounce
Provide a static debounce configuration mechanism for twl4030 GPIOs,
replacing the previous dynamic one. The single user of that mechanism was
for MMC card detect debouncing.
Boards can provide a bitmask saying which GPIOs to debounce (30 msec).
It's always enabled for pins with the MMC card-detect/VMMCx link active,
so most boards won't need to set the debounce mask.
This is a net code shrink, including runtime footprint.
