[Xen-devel] [PATCH] xen: arm: correct definition of DCISW (data cache invalidate by set/way)

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

We don't actually use this but I was using it locally for debugging and it
tripped me up.

Also add DCCIMVAC "data cache clean and invalidate by MVA" which is the only
cache op missing from cpregs.h.
