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.
