Initialise cpu ops after enabling data cache
The cpu-ops pointer was initialized before enabling the data cache in the cold
and warm boot paths. This required a DCIVAC cache maintenance operation to
invalidate any stale cache lines resident in other cpus.
This patch moves this initialization to the bl31_arch_setup() function
which is always called after the data cache and MMU has been enabled.
This change removes the need:
1. for the DCIVAC cache maintenance operation.
2. to initialise the CPU ops upon resumption from a PSCI CPU_SUSPEND
call since memory contents are always preserved in this case.
