arm64: ptrace: Use ARM64_SME to guard the SME register enumerations
commit eb9a85261e297292c4cc44b628c1373c996cedc2 upstream.
We currently guard REGSET_{SSVE, ZA} using ARM64_SVE for no good reason.
Both enumerations would be pointless without ARM64_SME and create two empty
entries in aarch64_regsets[] which would then become part of a process's
native regset view (they should be ignored though).
Switch to use ARM64_SME instead.
Fixes: e12310a0d30f ("arm64/sme: Implement ptrace support for streaming mode SVE registers")
