[U-Boot] [PATCH v1 12/16] usb: musb-new: Allow the diver not to use the set_phy_power() callback

[Jean-Jacques Hiblot]

The set_phy_power() callback is part of struct omap_musb_board_data. This
structure is part of the platform data passed to the musb-new driver. This
does not really fit with the Driver Model, so allow not to use struct
omap_musb_board_data to turn the phy on or off.
