phy: berlin-usb: adjust USB_PHY_RX_CTRL init flags
Make the value written into the USB_PHY_RX_CTRL configuration register match 0xAA79 value written by manufacturer-supplied kernels for Sony NSZ-GS7 (Berlin2 SoC), Google Chromecast and Valve Steam Link (BG2CD). This fixes timeouts communicating to the internal hub on Steam Link.
