With the patches of ILP32, COMPAT is not equivalent to AARCH32 in EL0.
This patch fix this by updating the dependency from COMPAT to
AARCH32_EL0 for ARMV8_DEPRECATED and ARM64_ERRATUM_845719.

I'd change the title of this patch: at this point in the series, the
dependency is not wrong yet, it just needs to be changed before
ARM64_ILP32 gets introduced.
