up_read() may wakeup some tasks, so do not call up_read() in scheduler,
or it will cause deadlock as below:

Since RK356x, the USB PHY GRF adds new registers to select
bvalid from USB PHY or GRF. And in RK356x Maskrom USB driver,
it selects the bvalid from GRF and sets the bvalid value to 1,
it aims to improve the compatibility of various USB circuits
for Maskrom USB. However, the charger detection and USB PHY
power consumption control depends on the bvalid of USB PHY.
So this patch selects bvalid from USB PHY for otg port.

If dwc3 failed to init ep0 in __dwc3_gadget_start(), the ep0state will
be uninitialized, aka, ep0state is EP0_UNCONNECTED, in this case, we
don't need to wait for control transfer completion when stop gadget
because no usb control transfer in process. This patch can help to avoid
the following warning in RK356x Boards during shutdown process.
