usb: musb: Disable pullup at init

commit 96a0c12843109e5c4d5eb1e09d915fdd0ce31d25 upstream.

The pullup may be already enabled before the driver is initialized. This
happens for instance on JZ4740.

It has to be disabled at init time, as we cannot guarantee that a gadget
driver will be bound to the UDC.
