ARM: OMAP: make legacy gpio request/free calls superfluous

Browse Source 
Clean up OMAP GPIO request/free functions

 - Rename and declare static OMAP specific GPIO request/free functions
 - Register them into gpiolib as chip-specific hooks
 - Add omap_request_gpio/omap_free_gpio wrappers for existing code not
   converted yet to use gpiolib
