Subject: [PATCH 0/4] arm64/sysreg: Clean up TCR_XXX field macros

Currently [V]TCR[1|2]_EL[1|2] sysreg field macros are sprinkled across the
arm64 platform code including KVM implementation. Clean these up via adding
required register filed definitions in tools sysreg format and subsequently
doing all necessary replacements. The cleanup does not cause any functional
change.

This applies on v6.17-rc2
