ARM: mach-shmobile: Tidy up the Kconfig bits.
Presently each one of the CPUs manually selects the same feature set, and
there's a reasonable expectation that none of these will change for
future CPUs in the SH-Mobile / R-Mobile family, so we move those over to
the top-level ARCH_SHMOBILE.
While we're at it, all of the CPUs support optional GPIOs via the PFC,
do not have I/O ports, and expect sparse IRQ, so we bring the
configuration in line across the board.
This more or less brings the ARM-based parts in sync with their SH
counterparts.
