gpiolib: avr32 at32ap platform support ...
Teach AVR32 to use the "GPIO Library" when exposing its GPIOs, so that signals
on external chips (like GPIO expanders) can easily be used.
This mostly reorganizes some existing logic, with two minor changes in
behavior:
- The PSR registers are used instead of the previous "gpio_mask" values,
matching AT91 behavior and removing some duplication between that role
and that of "pinmux_mask".
- NR_IRQs grew to acommodate a bank of external GPIOs. Eventually this
number should probably become a board-specific config option.
There's a debugfs dump of status for the built-in GPIOs, showing which pins
have deglitching, pullups, or open drain drive enabled, as well as the ID
string used when requesting each IRQ.
