Cover letter [PATCH 0/3] UEFI stub pre-boot compat checks

As discussed earlier today [1], and last year [2], it makes sense for the UEFI stub to perform some basic checks on the hardware for missing features that would prevent the kernel from booting to a state where it can even complain about this.

So implements this for ARM, to check on LPAE builds whether the CPU supports it (patch #1), and for arm64, to check whether the build time granule is implemented by the CPU (patch #2). Patch #3 wires it up into the shared init code.

Cheers
