Dimitris Papastamos 1d6d47a82a Optimize SMCCC_ARCH_WORKAROUND_1 on Cortex A57/A72/A73 and A75
This patch implements a fast path for this SMC call on affected PEs by
detecting and returning immediately after executing the workaround.

NOTE: The MMU disable/enable workaround now assumes that the MMU was
enabled on entry to EL3.  This is a valid assumption as the code turns
on the MMU after reset and leaves it on until the core powers off.
