Logitech Rally Bar devices, despite behaving as UVC cameras, have a
different power management system that the other cameras from Logitech.
USB_QUIRK_RESET_RESUME is applied to all the UVC cameras from Logitech
at the usb core. Unfortunately, USB_QUIRK_RESET_RESUME causes undesired
USB disconnects in the Rally Bar that make them completely unusable.
There is an open discussion about if we should fix this in the core or
add a quirk in the UVC driver. In order to enable this hardware, let's
land this patch first, and we can revert it later if there is a
different conclusion.

In order for display colorimetry to work correctly on DP displays
we need to send the VSC SDP packet. We should only do so for
panels with DPCD revision greater or equal to 1.4 as older
receivers might have problems with it.

From: Wenjing Liu <wenjing.liu(a)amd.com>
[why]
In current implemenation ODM mode is only reset when the last plane is
removed from dc state. For any dc validate we will always remove all
current planes and add new planes. However when switching from no planes
to 1 plane, ODM mode is not reset because no planes get removed. This
has caused an issue where we kept ODM combine when it should have been
remove when a plane is added. The change is to reset ODM mode when
adding the first plane.
