Usb-controller can invoke phy_power_on/off in its suspend/resume
process, so usb-phy need not do it again.
This adds remove phy_power_on/off in its suspend/resume cases.

DWC3 use extcon notifier to manage USB cable detection
and mode switch. For host mode, if USB device connected,
it requires to reset the whole DWC3 controller to make
sure that pipe power state in P2 before power on USB3 PHY,
after do DWC3 reset we will do phy power on in extcon evt
work, however, the DWC3 core will do phy power on again
in runtime resume process (dwc3_runtime_resume() ->
dwc3_core_init() -> phy_power_on()). This will cause PHY
power off failure during suspend because we just do once
phy power off in suspend(dwc3_suspend() -> dwc3_core_exit()
-> phy_power_off()).
This patch does phy power off in suspend to make sure that
USB2 PHY enter suspend in HOST mode. And because USB3 PHY
power on operation need to be done while the pipe is in P2
state, but after resume the pipe is in P0 state, so we just
put USB3 PHY in power on state.

One basic condition of usb remote wakeup is vbus on, so we add
regulator-always-on property for vcc5v0_host regulator in this adds.
In the previous codes, ehci/ohci-platform did not power off
vcc5v0_host regulator due to some oddish codes, and we have fixed it
at commit b5a0a9e8794d.

If the driver is in suspended mode, the dp block may be disabled, and
chip registers may not be accessible. Yet, the worker may be triggered

If no monitor is connected, suspend/resume cycles result in firmware
load errors because the driver attempts to load the firmware while
the system is in suspend state. This results in a kernel warning and
traceback.
Loading the firmware during boot fixes the problem. Note that we can not
just call schedule_work conditionally in cdn_dp_pd_event() if the insertion
status changed. The problem would still be seen if a monitor is connected
for the first time during suspend.

There is a uCPU in DP controller, it need a firmware to work,
please put the firmware file to /lib/firmware/rockchip/dptx.bin. The

mailbox to communicate with the ucpu.

In ehci/ohci-platform, phy_power_on() gets called twice at probe time,
one is at pdata->power_on(); another is in usb_add_hcd(). However,
phy_power_off() is only invoked one time when ehci/ohci-platform goes
to PM suspend. As a result, the phy power count become inconsistent.
This adds assigned phy phandle to hcd-phy at ehci/ohci-platform probe
time to prevent hcd invoking generic phy methods again when phy-cells
is 0 in DT.
