Subject: [PATCH 12/25] arm64: compat: change config dependences to aarch32

From: Bamvor Jian Zhang <bamvor.zhangjian@...aro.org>

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.
