usb: fixes for v3.4-rc cycle

A few more fixes for v3.4-rc cycle.

It includes a couple of fixes to the ordering of the methods in udc-core.c.
Without these two patches, we will have issues when either unregistering a
gadget driver (triggered with dummy_hcd only) or issuing a device-initiated
disconnect through sysfs.

There's also a fix on dummy_hcd to not call ->pullup() from udc_stop() because
udc-core.c already handles that.

A fix to MUSB as promised, to kill the compile warnings regarding deprecated
interfaces. We are essentially dropping the __deprecated flag because it
doesn't look like we will ever be able to live without it when we consider the
amount of silicon issues we find on different MUSB instantiations.

A couple of other fixes are also available, one adding the missing transceiver
events to gpio_vbus and another adding a missing unregister call to MUSB's
davinci glue layer.
