[PATCH 09/15] staging: rtl8723bs: remove unused code blocks conditioned by never set CONFIG_GPIO_API

[Fabio Aiuto <fabioaiuto83@gmail.com>]

remove conditional code blocks checked by unused
CONFIG_GPIO_API

cleaning required in TODO file:

find and remove code blocks guarded by never set CONFIG_FOO defines
