mtd: rawnand: Increment IFC_TIMEOUT_MSECS for nand controller response
Under heavy load it is likely that the controller is done
with its own task but the thread unlocking the wait is not
scheduled in time. Increasing IFC_TIMEOUT_MSECS allows the
controller to respond within allowable timeslice of 1 sec.
