GPIO: OMAP: Use wkup regs off/suspend support flag

Wakeup register offsets are initialized according to OMAP versions
during device registration. These explicit checks are no longer needed.

mpuio_init() function is defined under #ifdefs. It is required only in case
of MPUIO bank type and only when PM operations are supported by it.
This is applicable only in case of OMAP16xx SoC's MPUIO GPIO bank type.
For all the other cases it is a dummy function. Hence clean up the same
and remove all the OMAP SoC specific #ifdefs.

bank_is_mpuio() is defined as a check to identify if the bank type is MPUIO.
It is not required to define it separately as zero for OMAP2plus. Remove this.
