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.
