The new Rockchip socs have optional half divider,
so we use "branch_half_divider" + "COMPOSITE_NOMUX_HALFDIV \
DIV_HALF \ COMPOSITE_HALFDIV \ CMPOSITE_NOGATE_HALFDIV"
to hook that special divider clock-type into our clock-tree.

Indeed, "2EE" is hardcoded, it's not a good way.
But I could not find a way to get the number of EE(s) at runtime right now.

We need to close ADC or DAC mclk if they are not working,
it may reduce a bit of power consumption for runtime.
And, power off and close pclk_acodec during suspend. But
the acodec may be needed by VAD during suspend, we can
use the property 'rockchip,no-deep-low-power' to keep
codec during suspend.
The following is a comparison of power consumption before
and after the modification on RK3308 EVB v10:
[default] VCC_1V8_CODEC(V*mA=mW) VCC_3V3_CODEC(V*mA=mW)
idle 1.794*0.9=1.614 3.354*2.8=9.3912 // the ADC and DAC mclk are opened
playback 2ch 1.793*7.9=14.1647 3.354*2.8=9.3912 // the ADC and DAC mclk are opened
capture 8ch 1.789*27.8=49.7342 3.324*2.8=9.3072 // the ADC and DAC mclk are opened
suspend 1.8*0.7=1.26 3.356*2.8=9.3968 // the ADC and DAC mclk are opened
[modified] VCC_1V8_CODEC(V*mA=mW) VCC_3V3_CODEC(V*mA=mW)
idle 1.794*0.8=1.4352 3.354*2.8=9.3912 // just close ADC and DAC + close ADC / DAC mclk
playback 2ch 1.793*7.8=13.9854 3.354*2.8=9.3912 // open DAC mclk, close ADC mclk
capture 8ch 1.789*27.7=49.5553 3.323*2.8=9.3044 // open ADC mclk, close DAC mclk
suspend 1.799*1=1.799 3.355*0.3=1.0065 // close 2 micbiases, close mclk tx/rx and pclk_acodec
It seems that the light low power (close ADC and DAC mclk) can't
bring us much help to reduce power (only ~1mA@VCC_1V8_CODEC),
but the deep lower power can help us to reduce ~8mW@VCC_3V3_CODEC
during suspend. However, it's that the power is increased
~0.5mW@VCC_1V8_CODEC in deep low power, it needs to EE's to
help us to check this.

If XferNotReady comes before usb_ep_queue() we will
set our PENDING request flag and wait for a
request. However, originally, we were assuming
usb_ep_queue() would always happen before our first
XferNotReady and that causes a corner case where we
could try to issue ENDTRANSFER command before
STARTTRANSFER.
Let's fix that by tracking endpoints which have been
started.

(cherry picked from commit 6cb2e4e3de)
The cmd argument we pass to
dwc3_send_gadget_ep_cmd() could contain extra
arguments embedded. When checking for StartTransfer
command, we need to make sure to match only lower 4
bits which contain the actual command and ignore the
rest.
