The current HCR_EL2 description includes _EL1 registers that are not affected by NV. Let's exclude them from those ranges to implement a more fine grained approach.
Changes v1 -> v2 patch 1: fix indentation patch 2: improve commit message (Marc) fix indentation (Marc) follow kernel comment format (Marc) describe LRs in ranges (Marc) include AMEVCNTVOFF0<n>_EL2 and AMEVCNTVOFF1<n>_EL2 patch 3: drop. Excluded IMPDEF range is trapped by HCR_EL2.TIDCP
v1: https://lore.kernel.org/kvmarm/20230913185209.32282-1-miguel.luis@oracle.com/
