usb: musb: introduce struct musb_platform_ops
This will be passed to musb_core by platform glue layer in order to make it easier to compile support for several HW glue layers. Later patches will come using this structure and also moving HW glue layers to its own platform driver; the idea is to be able to handle platform peculiarities in a manner which doesn't affect one another.
