usb:ci_udc: Remove ULPI setting for i.MX OTG controller
All the i.MX6, i.MX23 and i.MX28 OTG controllers only support UTMI interface. Set to ULPI is not correct, even the controller will reject this setting in PORTSC register. Signed-off-by: Ye.Li <B37916@freescale.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
