davinci: am17x/da830/omap-l137 evm: setup NAND flash timing

Setup the NAND flash timings for DA830 EVM.

Before configuring the timing values, throughput calculation
using dd command yielded 477 kB/s write and 970 kB/s read speed.

After the timing configuration, the throughput was measured to
be 2.5 MB/s write and 5.1 MB/s read.

NAND datasheet]
