Subject: [PATCH 0/2] arm64: Add some missing userspace ABI documentation

I noticed that we've added HWCAP2_HBC without updating the
documentation, and in the process also noticed that some user visible
fields in ID_AA64ISAR2_EL1 are not documented.  Fix these issues.

Given the lack of any automatic generation or auditing there's almost
certainly more fields that are broken in cpu-feature-registers.rst, I
didn't check any other registers.
