driver for onboard buttons which occupy PA19 and PA20 lines.
this is very simple driver - it configures gpio pin on input
and toggles LED on every interrupt (when pressed) using devctl.

driver uses 'flags' on attachment to distinguish what minor instance of 'gpioled'
it should toggle. this allows two buttons to drive two leds :)
