The newer SoCs (rk3366, rk3399) take a different usb-phy IP block
than rk3288 and before, and most of phy-related registers are also
different from the past, so a new phy driver is required necessarily.

Changes in v2:
- Changed vbus_host operation from gpio to regulator in *_probe.
- Improved the fault treatment relate to 480m clock register.
- Cleaned up some meaningless codes in *_clk480m_disable.
- made more clear the comment of *_sm_work.

One more comment:
include/linux/clk-provider.h:#define CLK_IS_ROOT BIT(4) /*
Deprecated: Don't use */
... and the definition has been removed in linux-next.
also, the created clock should be a child of the phy-supply clock. Please take
a look at the picophy-variant (phy-rockchip-usb) that already handles that
parent assignment.
Okay, I will refer and correct them in the next patch (patch v3) .
BR.
