[PATCH V4 0/2] arm64/sysreg: Clean up TCR_EL1 field macros

[Anshuman Khandual]

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-rc4

- Fixed ARM ARM version from 7.B to L.B
- Changed UnsignedEnum into Enum per Mark
- Dropped all TCR_EL1 replacements from KVM code
- Moved existing TCR_XXX macros from (asm/pgtable-hwdef.h) into KVM header
