Add a function that sets up necessary data structures. In older kernels
this was done in a board_ file. To support initialization via a DT, this
now needs to be included in the probe() function.
Also declare a new device 'compatible' name (am35x-musb) to
differentiate it from omap3-musb.

These are common MUSB traits, so I think should be parsed by a generic
function. If at all -- they might be determined from the "compatible" prop.
