[PATCH V5 0/4] arm64/sysreg: Clean up TCR_EL1 field macros

Currently TCR_EL1 field macros are sprinkled across the arm64 platform code
including KVM implementation. Clean these up via updating required register
filed definitions in tools sysreg format and then subsequently doing all
necessary replacements. All required TCR_XXX macros have been moved from
(asm/pgtable-hwdef.h) into KVM header (asm/kvm_arm.h) for their continued
usage in KVM.

The cleanup does not cause any functional change.

This applies on v6.17-rc6
