tf-cov-make: For qemu_sbsa SPM_MM=1, add ENABLE_SME_FOR_NS=0

Otherwise, there's error during compilation:

01:28:25.194 services/std_svc/spm/spm_mm/spm_mm.mk:17: *** "Error: SPM_MM is not compatible with ENABLE_SME_FOR_NS".  Stop.

Looking at the mentioned *.mk, both ENABLE_SVE_FOR_NS and ENABLE_SME_FOR_NS
should be disabled (first was already, 2nd isn't).
