MFD: mcp-sa11x0: move setup of PPC unit out of mcp-sa11x0.c
Patch taken from af9081ae64 (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. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
