Ben Dooks 8a53bdb907 [ARM] S3C: Add GPIO chip tracking
The gpiolib driver keeps its chip array to itself
and having a separate array for s3c-only gpios stops
any non-s3c gpio being used in one of the s3c specific
configuration calls.

Ben Dooks f945ee13cf [ARM] S3C64XX: Fix warnings from map_io initilaisers
Discard the 'void *' from the pointers used for the
virtual addresses when setting up the .virtual fields
of the io map to avoid implicit cast warnings

Ben Dooks 39669f594e [ARM] S3C64XX: Reduce some output from INFO to DEBUG
Some of the startup output can be reduced to
KERN_DEBUG from KERN_INFO as it is only really
useful when trying to debug kernel initialisation
problems.

Ben Dooks 80789e7915 [ARM] S3C64XX: Add IRQ_EINT support
Add the necessary code to support IRQ_EINT(x) on
the S3C64XX series of CPUs.

Note, since there is no GPIO configuration support
in the kernel, the irq set_type method does not
configure the relevant pin to interrupt.
