da850evm: fix NAND WSTROBE and TA timings

The current NAND timings, introduced in commit
a3f88293ddd13facd734769c1664d35ab4ed681f da850evm: setup the NAND flash
timings , incorrectly set WSTROBE and TA to 0. A more recent inspection of the
values set by the Linux kernel indicates that these should be set to 1.

Set the WSTROBE and TA field of the EMIFA cycle-count timings configuration to
1 to match the values set by linux.
