ARM: dts: dm814x: dra62x: Disable wait pin monitoring for NAND
The NAND Ready/Busy# line is connected to GPMC_WAIT0 pin and
can't be used for wait state insertion for NAND I/O read/write.
So disable read/write wait monitoring as per Reference Manual's
suggestion [1].

[1] dm814x TRM: SPRUGZ8F: 11.2.4.12.2 NAND Device-Ready Pin
