Muhammad Usama Anjum 99c84311e3 x86/selftests: Skip the tests if prerequisites aren't fulfilled
Skip instead of failing when prerequisite conditions aren't fulfilled,
such as invalid xstate values etc.

Make the tests show as 'SKIP' when run:

  make -C tools/testing/selftests/ TARGETS=x86 run_tests

  ...
  # timeout set to 45
  # selftests: x86: amx_64
  # # xstate cpuid: invalid tile data size/offset: 0/0
  ok 42 selftests: x86: amx_64 # SKIP
  # timeout set to 45
  # selftests: x86: lam_64
  # # Unsupported LAM feature!
  ok 43 selftests: x86: lam_64 # SKIP
  ...

In the AMX test, Move away from check_cpuid_xsave() and start using
arch_prctl() to find out if AMX support is present or not. In the
kernels where AMX isn't present, arch_prctl() returns -EINVAL, hence it is
backward compatible.
