This breaks the build of the KVM selftests:

aarch64/aarch32_id_regs.c:150:16: error: use of undeclared identifier 'ID_AA64PFR0_EL1_ELx_64BIT_ONLY'
  150 |         return el0 == ID_AA64PFR0_EL1_ELx_64BIT_ONLY;
      |                       ^
1 warning and 1 error generated.

since it's pulled over the changes in 056600ff7330 ("arm64/cpufeature:
Replace custom macros with fields from ID_AA64PFR0_EL1") but not updated
the test to reflect this.
