Some USB managament on userspace (like Android system) rely on the uevents
generated by the composition driver to generate user notifications. Thus this
patch adds uevents to be generated whenever USB changes its state: connected,

The musb-core now a days always treats babble errors in host mode
as disconnects, so there is no need for the sunxi specific handling
of this anymore.

The sunxi musb has a bug where sometimes it will generate a babble
error on device disconnect instead of a disconnect irq. When this
happens the musb-controller switches from host mode to device mode
(it clears MUSB_DEVCTL_SESSION and sets MUSB_DEVCTL_BDEVICE) and
gets stuck in this state.
