Matthieu CASTET 4ebd089823 usb: chipidea: need to mask when writting endptflush and endptprime 
commit 5bf5dbeda2 upstream.

ENDPTFLUSH and ENDPTPRIME registers are set by software and clear
by hardware. There is a bit for each endpoint. When we are setting
a bit for an endpoint we should make sure we do not touch other
endpoint bit. There is a race condition if the hardware clear the
bit between the read and the write in hw_write.
