ARM: dts: am43xx-epos-evm: Don't use read/write wait monitoring
NAND uses wait pin only to indicate device readiness after a block/page operation. It is not use to extend individual read/write cycle and so read/write wait pin monitoring must be disabled for NAND. Add gpmc wait pin information as the NAND uses wait pin 0 for device ready indication.
