dm: gpio: Rename get_dir_flags() method to get_flags()

It is more useful to be able to read all the flags, not just the direction
ones. In fact this is what the STM32 driver does. Update the method name
to reflect this.

Tweak the docs a little and use 'flagsp' as the return argument, as is
common in driver model, to indicate it returns a value.
