MIPS: Ath79: Remove the unused GPIO function API

Browse source 
To prepare moving the GPIO driver to drivers/gpio remove the
platform specific pinmux API. As it is not used by any board,
and such functionality should better be implemented using the
pinmux subsystem just removing it seems to be the best option.
