fix(qemu): disable FEAT_SB

Browse source 
qemu/qemu_sbsa platforms support wide selection of cpu cores. From
Cortex-A57 (v8.0) to Neoverse-N2 (v9.0) one. Only the last one (and
'max' which supports everything possible) supports FEAT_SB.

Runtime check for ENABLE_FEAT_SB does not work in our case and we want
to have working platform.
