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.

Changes in v2:
- Rename HWCAP3_LUT6 to HWCAP3_SVE_LUT6 and make it depend on SVE.
- Rebase onto v7.1-rc3.
- Link to v1: https://patch.msgid.link/20260302-arm64-dpisa-2025-v1-0-0855e7f41689@kernel.org
