Currently, drivers have no mechanism to block requests to unbind
devices. However, this can cause resource leaks and leave the device in

We want programs besides the compositor to be able to enable or disable
panel power saving features. However, since they are currently only
configurable through DRM properties, that isn't possible. So, to remedy
that issue introduce a new "panel_power_savings" sysfs attribute.

If the sink supports 128b/132b and single-stream sideband messaging,
enable MST mode.
With this, the topology manager will still write DP_MSTM_CTRL, which
should be ignored by the sink. In the future,
drm_dp_mst_topology_mgr_set_mst() bool mst_state parameter should
probably be turned into an enum
Debug log the sink's MST capability, including single-stream sideband
messaging support, and the decision whether to enable MST mode or not.

Currently we've split MST capability detection in two places,
intel_dp_can_mst() and intel_dp_configure_mst(). They check essentially
the same things.
Move bulk of the work, including logging, to intel_dp_can_mst() and
rename it intel_dp_mst_detect(). Set intel_dp->is_mst there to avoid
duplicate
Amend drm_dp_read_mst_cap() to return an enum, indicating "none",
"sideband messaging", or "mst". Modify all call sites to take the new
return value into account.
