usb: musb: factor out hcd initalization
The musb struct is currently allocated along with the hcd, which makes it difficult to build a driver that only acts as gadget device. Fix this by allocating musb directly, and keep the hcd around as a pointer in the musb struct. struct hc_driver musb_hc_driver can now also be static to musb_host.c, and the macro musb_to_hcd() is just a pointer dereferencer for now, and will be eliminated later.
