ARM: OMAP2+: gpmc: Don't complain if wait pin is used without r/w monitoring
For NAND read & write wait pin monitoring must be kept disabled as the wait pin is only used to indicate NAND device ready status and not to extend each read/write cycle. So don't print a warning if wait pin is specified while read/write monitoring is not in the device tree. Sanity check wait pin number irrespective if read/write monitoring is set or not.
