musb_gadget: Fix for spurious interrupts on endpoint zero.
There is a multi-year old bug in the MUSB hardware which is not documented. It causes spurious interrupts and have various symptoms, like endless "SetupEnd came in a wrong ep0stage" messages. The fix is taken from the FreeBSD's musb driver. How to reproduce: For example issue clear-stall on a couple of endpoints very fast, like one request per 125us. After a while the bug triggers and the musb-chip becomes unusable until next re-enumeration.
