Andrei Cherechesu 6279b9a3be xen/arm: Enable workaround for Cortex-A53 erratum #1530924
All versions of Cortex-A53 cores are affected by the speculative
AT instruction erratum, as mentioned in the Cortex-A53 Revision r0
SDEN v21 documentation.

Enabled ARM64_WORKAROUND_AT_SPECULATE for all versions of Cortex-A53
cores, to avoid corrupting the TLB if performing a speculative AT
instruction during a guest context switch.
