kvm/arm: use PSR_AA32 definitions
Some code cares about the SPSR_ELx format for exceptions taken from AArch32 to inspect or manipulate the SPSR_ELx value, which is already in the SPSR_ELx format, and not in the AArch32 PSR format. To separate these from cases where we care about the AArch32 PSR format, migrate these cases to use the PSR_AA32_* definitions rather than COMPAT_PSR_*. There should be no functional change as a result of this patch. Note that arm64 KVM does not support a compat KVM API, and always uses the SPSR_ELx format, even for AArch32 guests.
