In dwc3_gadget_suspend(), if fail to stop DWC3 controller,
and return without do __dwc3_gadget_stop(), it will not
disable ep0 and ep1, and the dep->flags stays in the state
DWC3_EP_ENABLED, this will casue gadget connect failed.
A typical case is:
DWC3 works as DRD mode, fist plug in OTG HOST cable and
works as HOST mode, then plug out HOST calbe, after this
operation, it will do runtime supend -> dwc3_gadget_suspend()
-> dwc3_gadget_run_stop() fail -> return without stop gadget,
and then plug in OTG device cable, fail to connect with PC.

This patch adds runtime power management support for rockchip platform.
It depends on extcon notifier to do runtime resume and runtime suspend.
And since the dwc3 core dev is the only child of dwc3 rockchip dev, so
we need to ensure dwc3 core dev enter runtime suspend befer put dwc3
rockchip dev in runtime suspend. And after do runtime resume dwc3 core
dev, the PM core will resume dwc3 rockchip dev prior to dwc3 core dev
resume. With this patch, we can power off USB3 power domain and disable
clocks in runtime suspend.

Before reboot if the DCDC is disabled,
the DCDC is still disabled after restart.
We have an method to workaround:
Use vsel pin to switch the voltage between value in FAN53555_VSEL0
and FAN53555_VSEL1. If VSEL pin is inactive, the voltage of DCDC
are controlled by FAN53555_VSEL0, when we pull vsel pin to active,
they would be controlled by FAN53555_VSEL1.
In this case, we can set FAN53555_VSEL1 to disable dcdc,
So we can make vsel pin to active to disable dcdc,
VSEL pin is inactive to enable DCDC.

On vpu2 register separate interrupt bit and enable bit to different
register. When decoder found a buffer empty error which means the input
stream is not enough for one complete frame decoder will not stop
reading input stream buffer until it reach the end of buffer. This will
cause mmu fault on the buffer end.
In order to avoid this case decoder need to clear the enable bit in the
enable register to stop decoder from reading.
