The CLK_SET_RATE_PARENT flag make the parent clock and the child clk is 1:1.
If the DCLK frequency is too low, the PLL frequency will be very
low, which will affect the output waveform quality of PLL, and PLL
locking may be abnormal, so add a new COMPOSITE_DCLK clock-type to handle
that.

From Rockchips fractional divider usage, some clocks can be generated
by fractional divider, but the input clock frequency of fractional
divider should be less than a specified value.

[ 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XferNotReady, so the frame number is outdated and start transfer fail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 Otherwise the frame number is outdated and start transfer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.
