usb: chipidea: need to mask when writting endptflush and endptprime
commit 5bf5dbeda2454296f1984adfbfc8e6f5965ac389 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.
