This is known issue where movntdqa support is disabled for hypervisor.
GuC init/load is currently tied up with logging setup that depends on
movntdqa.
Michal Winiarski will be sharing new changes for GuC log/relay support
and then we can bypass this check for GuC load.
Can use this meanwhile https://patchwork.freedesktop.org/patch/205723/
for CI.
