Saradc interrupt status may exist forever if read saradc
when system suspending which disable clock that finally
lead to interrupt system dead. Add mutex in suspend to
avoid this issue.

This patch changes the function uvc_video_pump to be a separate
scheduled worker. This way the completion handler of each usb request
and every direct caller of the pump has only to schedule the worker
instead of doing the request handling by itself.
Moving the request handling to one thread solves the locking problems
between the three queueing cases in the completion handler, v4l2_qbuf
and video_enable.
Many drivers handle the completion handlers directly in their interrupt
handlers. This patch also reduces the workload on each interrupt.
Test on RK3568 EVB1 USB 3.0 UVC, use the high priority dedicated
workqueue instead of the system_wq can help to improve the uvc
transfer performance.

(cherry picked from commit 43cd002387)
If miss isoc event happens, the current code just move the
current req to the tail of the pending list, and then stop
the active transfer with cmd DWC3_DEPCMD_ENDTRANSFER. After
these operations, the isoc endpoint wait for a XferNotReady
event to restart the transfer with the first pending req
from the pending_list.
If there are already reqs in the pending list when move the
miss isoc reqs to the tail of the pending list, some of the
reqs are out of order.
This patch first moves all of the reqs in the started list
to the tail of the cancelled list, and then move all of the
reqs in the pending list to the tail of the cancelled list.
At last move all of the reqs in the cancelled list to the
pending list. This can make sure all of the reqs are in order
when restart the isoc transfer later.

Linux system will set hdmi properties when system boot
When some properties such as quant_range was set, dw_hdmi_setup()
will be called. HDMI status may not be config correctly. So if HDMI
is not properly initialized, don't call dw_hdmi_setup() when
these properties was set.

This reverts commit 20d8a7925f.
Generally, we cannot guarantee that the paths of capture and
playback need to be turned on by default after resume, which
can be manually controlled by the user layer. In this way, the
problem of asymmetrical clock operation can also be corrected
after resume.

Allow codec driver register callback function for plug event.
The callback registration flow:
dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec
dw-hdmi-i2s-audio implements hook_plugged_cb op
so codec driver can register the callback.
dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device
can register the callback.
When connector plug/unplug event happens, report this event using the
callback.
Make sure that audio and drm are using the single source of truth for
connector status.
