[ARM] 4109/2:  Add support for the RealView/EB MPCore revC platform

The kernel originally supported revB only. This patch enables revC by
default and adds a config option for building the kernel for the revB
platform. Since the SCU base address was hard-coded in the proc-v6.S
file (and only valid for RealView/EB revB), this patch also adds a
more generic support for defining the SCU information.
