Patch taken from af9081ae (ARM: sa1100: Refactor mcp-sa11x0 to use
platform resources.) by Jochen Friedrich <jochen@scram.de>, and
consolidated to use a common function.

Move the setup of the PPC unit out of mcp-sa11x0 into the core SA11x0
code, and call it from each platforms initialization file.  This
centralizes the setup of the PPC unit while not polluting the mcp-sa11x0
driver with these details.

Hook these platforms restart code into the new restart hook rather
than using arch_reset().

Everything should now be using sparsemem rather than discontigmem, so
remove the code supporting discontigmem from ARM.

Only register devices if we have platform data for those which require
platform data.

This adds gpiolib support for the SA-1100 arch:
 - Move all GPIO API functions from generic.c into gpio.c
 - Convert all gpio functions into gpiolib callbacks.

Add platform device data for the SA11x0 MCP device.  This allows
platforms to customise the configuration of the SA11x0 MCP device
according to their needs.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
