ARM: at91/pio: add new PIO3 features
This patch adds the support for new PIO controller found on some
at91sam SOCs.
- more peripheral multiplexing
- more features to configure on a PIO (pull-down, Schmitt trigger, debouncer)
- support for several IRQ triggering features (type and polarity)
Support for those new features are retrieved from the device tree
compatibility string.
Debugfs at91_gpio file is updated to monitor configuration.
