Disable UFS related clock in runtime is proved to be incorrect and
mismatch state between host and device should be recovered by reset the
controller to make sure each part is in the beginning status.
Meanwhile, we have verified WB works fine by test, so add WB support
as well.

When both CC1 and CC2 pins are simultaneously pulled up, it often leads
to the double Rp to Vbus cable being stuck in the SNK_ATTACH_WAIT state.
And the state machine fails to transition to the SNK_ATTACHED state.
Therefore, it is recommended to focus on transitioning the sink port to
the SNK_DEBOUNCED state instead. By doing so, the desired outcome can be
achieved more effectively.

The USB Type-C Cable and Connector Specification defines the wire
connections for the USB Type-C to USB 2.0 Standard-A cable assembly
(Release 2.2, Chapter 3.5.2).
The Notes says that Pin A5 (CC) of the USB Type-C plug shall be connected
to Vbus through a resister Rp.
However, there is a large amount of such double Rp connected to Vbus
non-standard cables which produced by UGREEN circulating on the market, and
it can affects the normal operations of the state machine easily,
especially to CC1 and CC2 be pulled up at the same time.
In fact, we can regard those cables as sink to avoid abnormal state.

In upstream patch, runtime pm is used to avoid excessive unprepare/
prepare.
However, some DSI panels need to be powered off and on again before
reloading the initialization sequence. If set the auto_suspend and
delay time is set to 1s, the suspend/resume callback function cannot
be entered when sleeping/waking up quickly, the power of panel cannot
be restarted, causing this timing to be abnormal and causing the panel
to not work properly.
In kernel 5.10, pm_runtime has not been used in panel-simple, but it
still runs stably in panel applications. Considering the above
reasons, we chose to revert the submission of pm_runtime upstream.
