ARM: add initial support for Picochip picoXcell SoC

[Jamie Iles]

Hi,

This patch series adds support for the Picochip picoXcell series of
femotcell SoC's. There are currently two device families - PC3X2 and
PC3X3. Both include an ARM1176JZ-S, 100Mb Ethernet controller, 2xDMA
controllers, eFuses, crypto offload engines and Picochip's array
processor the picoArray. This patch series adds support for the base
chip support including timers, gpio, pin muxing, clocks and pm and also
the PC7302 development board that can take either PC3X2 or PC3X3 devices.

This patch series is based off of linux-next (next-20101122) and also requires
the following patches:

    - 8250: add a UPIO_DWAPB32 for 32 bit accesses (v2):

    - debug-8250: add a 32 bit mode:
