According to the documentation gpio_free should only be called from task
context only. To make this more explicit add a might sleep to all
implementations.
This patch changes the gpio_free implementations for the x86
architecture.

This patch is the result of an automatic script that consolidates the
format of all the headers in include/asm-x86/.
The format:
1. No leading underscore. Names with leading underscores are reserved.
2. Pathname components are separated by two underscores. So we can
distinguish between mm_types.h and mm/types.h.
3. Everything except letters and numbers are turned into single
underscores.

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.
