drm/xe/pf: Enable SR-IOV PF mode by default 

We already claim official support for SR-IOV PF/VF modes on PTL
and BMG platforms, but by default we start the Xe driver on those
platforms in non-virtualized mode (native) since we still have
max_vfs modparam set to disable creation of the VFs.

It's time to let the Xe driver support SR-IOV PF mode by default.
We were already testing this on our CI, which was relying on the
patch that was enabling it for CONFIG_DRM_XE_DEBUG used by our CI.
