davinci: dm644x evm: setup NAND flash timing
The DM644x EVM nand flash timing was earlier being done as a special case in the NAND driver itself. With the NAND driver now capable of progamming the AEMIF interface using timing data passed from the platform, the timing values are being moved into their rightful place in the EVM specific board file. The values being programmed match what was being done earlier and thus do not represent any change in performance/functionality.
