USB: pxa27x_udc: add vbus_draw callback
Add the vbus_draw() callback to inform the transceiver, if it exists, how much current may be drawn. The decision is taken on gadget driver side using the configuration chosen by the host and its bMaxPower field. Some systems can use the host's VBUS supply to augment or recharge a battery. (There's also a default of 100 mA for unconfigured devices, or 8 mA if they're OTG devices.)
