drm/xe: Enable SR-IOV for ADL/ATSM

drm/xe: Enable SR-IOV for ADL/ATSM

We were already testing those two platforms for a while on our CI,
but enabling flag (has_sriov) was only available on the topic branch
and only for builds with CONFIG_DRM_XE_DEBUG config.

Since those two platforms are guarded by the another enabling flag
(require_force_probe) and we believe our SR-IOV support for them is
at sufficient level to start enjoying the feature, turn on the
SR-IOV enabling flag unconditionally.
