This patch adds uvc_function_suspend and uvc_function_resume
for uvc function. With this patch, if usb bus enter suspend
or resume state, the usb controller driver will call the
uvc_function_suspend or uvc_function_resume to send event
to uvc app.

The spi which's version is higher than ver 2 will automatically
enable this feature.
If the length of master transmission is uncertain, the RK spi slave
is better to automatically stop after cs inactive instead of waiting
for xfer_completion forever.

When system restart, there are two rst actions of PMIC sleep if
board hardware support:
- 0b'00: reset the PMIC itself completely.
- 0b'01: reset the 'RST' related register only.
In the case of 0b'00, PMIC reset itself which triggers SoC NPOR-reset
at the same time, so the command: reboot load/bootload/recovery, etc
is not effect any more.
We add a cmd list to check if this reboot cmd is what we expect for 0b'01.

[ 1589.834992] Failed to queue request (-22).
It's because that the __dwc3_gadget_start_isoc is called very late after
XferNotReady, so the frame number is outdated and start transfer fail
with the cmd_status "DEPEVT_TRANSFER_BUS_EXPIRY". In this case, the dwc3
driver return -EINVAL to the UVC function driver without delete and unmap
the failed request, this cause the request requeue fail next time.

Currently __dwc3_gadget_start_isoc must be called very shortly after
XferNotReady. Otherwise the frame number is outdated and start transfer
will fail, even with several retries.
DSTS provides the lower 14 bit of the frame number. Use it in combination
with the frame number provided by XferNotReady to guess the current frame
number. This will succeed unless more than one 14 rollover has happened
since XferNotReady.
Start transfer might still fail if the frame number is increased
immediately after DSTS is read. So retries are still needed.
Don't drop the current request if this happens. This way it is not lost and
can be used immediately to try again with the next frame number.
With this change, __dwc3_gadget_start_isoc is still not successfully in all
cases bit it increases the acceptable delay after XferNotReady
significantly.
