Just adding its own platform_driver, not really
using it yet.
When all HW glue layers are converted, more patches
will come to split power management code from musb_core
and move it completely to HW glue layer.

Er, we need a separate platfrom device for DA8xx now... Wait!
davinci_setup_usb() doesn't register platform device for DA8xx,
da8xx_register_usb20() does it. This is completely wrong then...
