usb: host: ehci-vf: Implement board_usb_phy_mode weak function
Add board_usb_phy_mode weak function on similar lines to ehci-mx6. However since Vybrid USB does not have a true OTG, make this weak functon just return 0. The function is supposed to be implemented by the individual boards using a GPIO for providing the OTG pin functionality. Signed-off-by: Sanchayan Maity <maitysanchayan@gmail.com>
