These patches add support for the GE IMP3A. This board (based on a Freescale
P2020) uses some support for FPGA logic common with the PPC9A and other 86xx
based boards, so this support has been moved out of the 86xx directory. A
config option (GE_FPGA) has been added to reduce churn on dependant drivers
(such as the watchdog timer) when further boards are added.
Move the GE GPIO and PIC drivers to allow these to be used by non-86xx
boards.
