usb: renesas_usbhs: fixup interrupt status clear method 



When interrupt happened, renesas_usbhs driver gets irq status
by usbhs_status_get_each_irq(), and cleared all status by using 0.
But, this method is incorrect,
since extra interrupt might occur between them.
This patch cleared corresponding bits only
