Subject: arm64: docs: cpu-feature-registers: Document ID_AA64PFR1_EL1

Git-commit: ade12b8631d91b9c2849facb0a1dc3af317ecbb3
Patch-mainline: v5.5-rc1
References: jsc#13705,jsc#13695

Commit d71be2b6c0e1 ("arm64: cpufeature: Detect SSBS and advertise
to userspace") exposes ID_AA64PFR1_EL1 to userspace, but didn't
update the documentation to match.

Add it.
