phy-sun4i-usb now has proper dr_mode handling, it always registers an

So we can simply the sunxi musb glue by always registering its extcon
notifier and relying on sunxi_musb_work() to enable vbus when in
host-only mode.
This also enables host- and peripheral-only mode with vbus monitoring.

It's been a bit painful to track all the patches needed so that it
applies properly, but I've finally been able to test it on a Sinlinx
SinA33 with peripheral-only mUSB, and it works like a charm.
You can add my Tested-by.
Great, thanks for testing.
This is the board which has an otg connector with vbus not connected,
right? Yet it does have a functional id-pin, right ?
In that case you should be able to put it in dual-role mode (only
specify the id-pin in the phy dts node, no vbus / vbus-monitoring)
and then it _should_ work in host mode if you use a powered hub.
I'm fine with putting in peripheral-only mode, but as said
dual-role might work with a powered hub.

Hans
