usb: dwc3: remove LPM L2 OUT interrupt



when LPM L2 OUT interrupt happen, need to clear state bit for new,
but there is issue for old code: irq_stat |= PWR_EVNT_LPM_OUT_L2_MASK;,
acctually it should be: irq_clear |= PWR_EVNT_LPM_OUT_L2_MASK;,
old code do nothing, it just test bit -> clear bit --> set bit,
remove old code will keep old behaviour.
