mtd: rawnand: Increment IFC_TIMEOUT_MSECS for nand controller response

[ Upstream commit 923fb6238cb3ac529aa2bf13b3b1e53762186a8b ]

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.
