Because USB OTG id irq is disabled during system suspend
and enabled after resume, so the usb2 phy doesn't notice
any id status change upon resume. It may cause two issues:
1. Plug in OTG cable and USB device when system enter
suspend, it will fail to detect the OTG cable and
USB device after resume.
2. Plug out OTG cable and USB device when system enter
suspend, and then connect USB to PC or USB charger
after resume, it will fail to detect USB charge type.
This patch restores the OTG id status before enter suspend，
and check the id status upon resume, and set the extcon
state and vbus if id status has changed.

There is only one snd_soc_card instance, the parameters that
include card name are overwritten, so that the DUT will be
hung during suspend that dues to snd_power_wait enter twice
because it find the incorrect node name "/vad-sound":
[ 14.129501] snd_power_wait, state: 0x0000, np name: /vad-sound
...
[ 14.133063] snd_power_wait, state: 0x0300, np name: /vad-sound
Then the "rockchip,rk3308-vad" has been off (SNDRV_CTL_POWER_D3 0x0300),
and enter endless loop in snd_power_wait().
Therefore, we need create independent snd_soc_cards
for multi-codecs, and find the corrent card name
during suspend:
[ 8.939576] snd_power_wait, state: 0x0000, card name: /vad-sound
...
[ 8.941472] snd_power_wait, state: 0x0000, card name: /acodec-sound

In previous code, driver will update the power supply status before
power_supply_register, so it will cause kernel panic. So we put the
bq25700_power_supply_init before bq25700_init_usb to fix this issue.

According to gt1x_generic.h, the GTP_POWER_CTRL_SLEEP is for
"turn off power on suspend" case.
And we're turning off TS's power on suspend actually.

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.

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.
