Jean-Christophe PLAGNIOL-VILLARD 21d08b9d55 at91: introduce commom AT91_BASE_SYS
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

Jean-Christophe PLAGNIOL-VILLARD 3d51f259e8 at91: drop boot_params and PLAT_PHYS_OFFSET
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

Christian Glindkamp c20b4dd318 at91: Refactor Stamp9G20 and PControl G20 board file
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.

Nicolas Pitre 6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

Christian Glindkamp 9b404b7cc3 ARM: 6054/1: AT91: taskit PortuxG20 and Stamp9G20 board support
Both boards share the same board file, as the PortuxG20 is basically an
SBC based on the Stamp9G20.
