Will Deacon 8e32fed034 arm64: cpufeature: Relax checks for AArch32 support at EL[0-2]
[ Upstream commit 98448cdfe7 ]

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.
