Paul Mundt 6d72ad35f1 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.

This sets the default memory size assumed by your kernel. It can

Allows the configuration of the timer frequency. It is customary
to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
case of low timer frequencies other values may be more suitable.
SH-Mobile systems using a 32768 Hz RCLK for clock events may want
to select a HZ value such as 128 that can evenly divide RCLK.
A HZ value that does not divide evenly may cause timer drift.
