phy: usb: Add support for new Synopsys USB controller on the 7216 The 7216 has the new USB XHCI controller from Synopsys. While this new controller and the PHY are similar to the STB versions, the major differences are: - Many of the registers and fields in the CTRL block have been removed or changed. - A new set of Synopsys control registers, BCHP_USB_XHCI_GBL, were added. - MDIO functionality has been replaced with direct access registers in the BCHP_USB_XHCI_GBL block. - Power up PHY defaults that had to be changed by MDIO in previous chips will now power up with the correct defaults. A new init module was created for this new Synopsys USB controller. A new compatible string was added and the driver will dispatch into one of two init modules based on it. A "reg-names" field was added so the driver can more easily get optional registers. A DT bindings document was also added for this driver.
