mtd: rawnand: mtk: Add validity check for CE# pin setting
Currently, we only check how many CE# pins are set in device tree.
But it should be necessary to check whether CE# pin setting is
duplicated or if CE# pin index exceeds the maximum CE# number that
controller supports.
So, add validity check to avoid these invalid settings.
