[PATCH v4 01/43] arm64: sysreg: Add ID_AA64ISAR1_EL1.LS64 encoding for FEAT_LS64WB

[Marc Zyngier]

The 2024 extensions are adding yet another variant of LS64
(aptly named FEAT_LS64WB) supporting LS64 accesses to write-back
memory, as well as 32 byte single-copy atomic accesses using pairs
of FP registers.

Add the relevant encoding to ID_AA64ISAR1_EL1.LS64.
