ENGR00152915-1 mx6q-usb: refine usb phy usage
(Fixed the bug that PLL7 lock failed after usb enters low power mode)
After confirming with IC guys, the phy clock should be used
like below:
- OTG phy clock
EN_USB_CLKS: should be also enabled
PLL3 power: Enable/Disable on the fly
- Host1 phy clock
EN_USB_CLKS and PLL7 power should be also enabled at the initialization
PLL7 power will be totally controller by IC
