There is no need to pinmux the UART so early in the kernel.
Move it to the board init.
This will also allow to finally move the gpio driver to platform device/driver.

Both at91 and avr32 defines its own platform data structure for
the macb driver and both share common structures though at91
includes a currently unused phy_irq_pin. Create a common
macb_platform_data for macb that both at91 and avr32 can use. In
future we can use this to support other architectures that use the
same IP block with the macb driver.
v2: rename eth_platform_data to macb_platform_data and allow at91_ether
to share the platform data with macb.

On all at91 except rm9200 and x40 have the System Controller starts
at address 0xffffc000 and has a size of 16KiB.
On rm9200 it's start at 0xfffe4000 of 111KiB with non reserved data starting
at 0xfffff000
This patch removes the individual definitions of AT91_BASE_SYS and
replaces them with a common version at base 0xfffffc000 and size 16KiB
and map the same memory space

select ARM_PATCH_PHYS_VIRT
as with ARM_PATCH_PHYS_VIRT you can patch boot_params at runtime or any recent
bootloader will provide a valid atags pointer in r2
as point out by Russell on AT91 we never use XIP
so se do not need PLAT_PHYS_OFFSET

switch early init to init_early and introduce soc map_io
with this Patch we will not do any more early device setup during the map io
tks to Russell to point the new call back

As PControl G20 is a carrier board for the Stamp9G20 SoM, some code can
be shared. Therefore board-stamp9g20.c is refactored to allow reusing the
SoM initialization and board-pcontrol-g20.c is modified to use it.
