Currently the dp-mst connector is created and destroyed dynamically,
which requires drm client to handle hot-plug and update the whole
connector list when device is connected or disconnected.
A reservation approach is added to allow connector to be created statically
for mst port in devicetree at system startup stage, and drm client can
control the connector in the same way as non-mst connectors. This optional
devicetree property is useful for system with a built-in mst-hub, and can
simplify the drm client design.

While running the DisplayPort simulation, if the simulation is
abruptly switched off, AUX and CTRL may continue processing
like in a normal DisplayPort connected mode. This may result
in an unstable DP driver state and may affect subsequent hot
plugs.
Abort the AUX and CTRL processing when DP simulation is
switched off. This brings the DP driver into stable state when
simulation is switched off.

The current driver implementation delays the connect_work until drm client
initializations are complete. This is performed to avoid sending hpd event
notification to drm client when hpd is connected before drm client is
initialized as it may cause drm client to miss the hpd event notification
and may not able to create the display. This delayed connect_work not
required anymore as drm client can handle plug-in display creation based
on the connector status reported from drm_get_connector api.
This change removes dp_display_post_open operations from driver
as this functionality is not required anymore as explained.

The current assumption for the 11ad ref_clk to be rf_clk3 is wrong,
as in some platforms another clk source is used.
Update the name to a more generic one.

On some platforms there is a LDO that powers the 11ad card,
this LDO behave same as other LDO's.
Update the vddio minimum voltage.
