OMAP/gpio: drop MPUIO static base

Browse Source 
The OMAP GPIO driver hardcodes the MPIO chip base, but there
is no point: we have already moved all consumers over to using
descriptor look-ups.

Drop the MPUIO GPIO base and use dynamic assignment.

Root out the unused instances of the OMAP_MPUIO() macro and
delete the unused OMAP_GPIO_IS_MPUIO() macro.
