[PATCH 0/3] KVM: selftests: arm64: Improve diagnostics from set_id_regs

While debugging issues related to aarch64 only systems I ran into
speedbumps due to the lack of detail in the results reported when the
guest register read and reset value preservation tests were run, they
generated an immediately fatal assert without indicating which register
was being tested. Update these tests to report a result per register,
making it much easier to see what the problem being reported is.
A similar, though less severe, issue exists with the validation of the
individual bitfields in registers due to the use of immediately fatal
asserts. Update those asserts to be standard kselftest reports.
