usb: gadget: s3c-hsotg: fix interrupt configuration in dedicated-fifo…
… mode In dedicated-fifo mode TxFIFOEmpty interrupt should be asserted when TxFIFO for this endpoint is completly empty, so NPTxFEmpLvl and PTxFEmpLvl bits are set in GAHBCFG register. In DIEPMSK register INTknTXFEmpMsk is set, becouse it's needed to indicate FIFO Empty state.
