[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.
