fsl/usb: Add controller version based ULPI and UTMI phy support
Add support for ULPI and UTMI PHYs based on usb controller version info read from device-tree Example of USB Controller versioning info: Version 1.2 and below : MPC8536, MPC8315, etc Version 1.6 : P1020, P1010, P2020, P5020, etc Version 2.2 : PSC9131, PSC9132, P3060, etc No changes for non-DT users Signed-off-by: Ramneek Mehresh <ramneek.mehresh@freescale.com> Acked-by: Li Yang <leoli@freescale.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
