[PATCH v2 0/2] arm64: Implement support for 2025 dpISA extensions

[Mark Brown]

The 2025 dpISA extensions introduce a number of architecture features
all of which are fairly straightforward from a kernel point of view
since they only introduce new instructions, not any architecture state.

- Rename HWCAP3_LUT6 to HWCAP3_SVE_LUT6 and make it depend on SVE.
