rdc321x: GPIO routines bugfixes
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.
