Subject: arm64: sysreg: Add some field definitions for PAR_EL1

Git-commit: e8620cff99946ea1f7891d7bec071a23a1fdaef3
Patch-mainline: v5.4-rc1
References: jsc#13705,jsc#13695

PAR_EL1 is a mysterious creature, but sometimes it's necessary to read
it when translating addresses in situations where we cannot walk the
page table directly.

Add a couple of system register definitions for the fault indication
field ('F') and the fault status code ('FST').
