[PATCH] arch: mips: ath79: gpio: Remove some unused functions

[Rickard Strandqvist <rickard_strandqvist@xxxxxxxxxxxxxxxxxx>]

Removes some functions that are not used anywhere:
ath79_gpio_function_disable() ath79_gpio_function_enable()

This was partially found by using a static code analysis program called cppcheck.
