Impact: cleanup

Move/remove leftover RDC321 files. Now that it's not a subarch anymore,
arch/x86/mach-rdc321x and arch/x86/include/asm/mach-rdc321x/ are not
needed.

One include file was still in use: rdc321x_defs.h, move that to the
generic x86 asm header directory.

This patch fixes the use of GPIO routines which are in the PCI
configuration space of the RDC321x, therefore reading/writing
to this space without spinlock protection can be problematic.

We also now request and free GPIOs and support the MGB100
board, previous code was very AR525W-centric.

This patch adds support for the RDC R-321x system-on-chip,
also known as R-861x-(G). It uses the generic GPIO API and
has support for the on-chip hardware watchdog.
