Cortex A9:errata 794073 workaround

On Cortex A9 an errata can cause the processor to violate the rules for
speculative fetches when the MMU is off but branch prediction has not
been disabled. The workaround for this is to execute an Invalidate
Entire Branch Prediction Array (BPIALL) followed by a DSB.

Workaround for CVE-2017-5715 for Cortex A9, A15 and A17

A per-cpu vbar is installed that implements the workaround by
invalidating the branch target buffer (BTB) directly in the case of A9
and A17 and indirectly by invalidating the icache in the case of A15.

For Cortex A57 and A72 there is currently no workaround implemented
when EL3 is in AArch32 mode so report it as missing.

For other vulnerable CPUs (e.g. Cortex A73 and Cortex A75), there are
no changes since there is currently no upstream AArch32 EL3 support
for these CPUs.

Support ARMv7 architectures

ARMv7: introduce Cortex-A9

As Cortex-A9 needs to manually enable program flow prediction,
do not reset SCTLR[Z] at entry. Platform should enable it only
once MMU is enabled.
