I/O processors: * The i80200 and the i80321 have the same CPU ID, so split the CPU_XSCALE option into CPU_XSCALE_80200 and CPU_XSCALE_80321 options, and don't let them both be defined at the same time. XXX May want to revisit this in the future. * Split some registers common between the i80200 and i80321 into <arm/xscale/xscalereg.h>. * Rename a few existing functions.
