[ Upstream commit 98448cdfe7060dd5491bfbd3f7214ffe1395d58e ]
We don't need to be quite as strict about mismatched AArch32 support,
which is good because the friendly hardware folks have been busy
mismatching this to their hearts' content.
* We don't care about EL2 or EL3 (there are silly comments concerning
the latter, so remove those)
* EL1 support is gated by the ARM64_HAS_32BIT_EL1 capability and handled
gracefully when a mismatch occurs
* EL0 support is gated by the ARM64_HAS_32BIT_EL0 capability and handled
gracefully when a mismatch occurs
Relax the AArch32 checks to FTR_NONSTRICT.
