rS338962: Export ID_AA64PFR0_EL1 to userland
rS338961: Move the undefined instruction handler to identcpu.c so we have access
Summary

Move the undefined instruction handler to identcpu.c so we have access
to the registers read on boot.

Use these to set the fields on the value of the ID_AA64PFR0_EL1 register
we export to userspace.

Test Plan

Read the registers with https://github.com/zxombie/arm64id
