[PATCH V5 1/4] tools: header : arm64: Replace TCR_NFD[0|1] with TCR_EL1_NFD[0|1]

From: Anshuman Khandual <hidden>
Date: 2025-09-21 00:53:21
Also in: kvmarm, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

Replace TCR_NFD[0|1] (used in TCR_CLEAR_FUJITSU_ERRATUM_010001) with field
definitions which are available in tool sysreg format. Helps in completely
dropping off the adhoc TCR_NFD[0|1] macros later.
