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.
