-Some quirky UDCs (like dwc3 on Exynos) need to have their phys calibrated e.g.
-for using super speed. This patch adds a new phy_calibrate() method.
-When the calibration should be used is dependent on actual chip.
-
-In case of dwc3 on Exynos the calibration must happen after usb_add_hcd()
-(while in host mode), because certain phy parameters like Tx LOS levels
-and boost levels need to be calibrated further post initialization of xHCI
-controller, to get SuperSpeed operations working. But an hcd must be
-prepared first in order to pass it to usb_add_hcd(), so, in particular, dwc3
-registers must be available first, and in order for the latter to happen
-the phys must be initialized. This poses a chicken and egg problem if
-the calibration were to be performed in phy_init(). To break the circular
-dependency a separate method is added which can be called at a desired
-moment after phy intialization.
