MLK-11123-10 usb: gadget: add otg descriptor allocate and init interface
Allocate usb otg descriptor and initialize it according to gadget's otg
capabilities, if usb_otg_caps is not set, keep settings as current gadget
drivers. With this 2 new interfaces, gadget can use usb_otg_descriptor
for OTG 1.x, and usb_otg20_descriptor for OTG 2.0 or above, and otg
features can be decided by the combination of usb hardware property
and driver config.
