[PATCH v2 5/8] usb: musb: omap2430: Don't use omap_get_control_dev()

[Roger Quadros]

omap_get_control_dev() is being deprecated as it doesn't support
multiple instances. As control device is present only from OMAP4
onwards which supports DT only, we use phandles to get the
reference to the control device.
