Mark Brown 0cab5b4964 arm64/sme: Fix context switch for SME only systems 
When refactoring fpsimd_load() to support keeping SVE enabled over syscalls
support for systems with SME but not SVE was broken. The code that selects
between loading regular FPSIMD and SVE states was guarded by using
system_supports_sve() but is also needed to handle the streaming SVE state
in SME only systems where that check will be false. Fix this by also
checking for system_supports_sme().
