- prepend CS3 accessors by simpad_ to indicate they
are specific to simpad devices.
- use spinlock to protect shadow register.
- implement 8 read-only pins.
- use readl/writel macros so barriers are used where
necessary.
- register CS3 as GPIO controller with 24 pins
(16 output only and 8 input only).
- fix PCMCIA driver to access the read-only pins
rather than the shadow register for status bits.
