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.
