Almost of the bits that are defined in the MXS USBPHY_CTRL register are not
defined in the Digicolor one. Some have different meaning, and some are
reserved. OTOH, the Digicolor USBPHY_CTRL register uses all bits in the 1-13
range. Also, the Digicolor phy does not have anatop registers.

Thanks.
BTW, do you know why the phy-mxs-usb driver calls its init from
postcore_initcall? Is there a special need to register the driver so early?
