Last point on this is that I think we want to sanitize PJ4.

If we think about CPU_V7 as being the selection of ARM CPUs which are V7
architectures, CPU_PJ4 should be a separate config option selecting all
the same symbols which CPU_V7 does - and that should also select proc-v7.S
for building.

I'm not sure it makes sense to have (eg) the V7 perf events available on
PJ4 or the ARM errata for their V7 cores?

Does PJ4 have VFPv3?  Is Neon available on PJ4?  What about the DCC
debug registers?
