Putting board_nand_init() function inside NAND driver was not appropriate due to it doesn't allow board vendor to customise their NAND initialization code such as adding NAND lock/unlock code.
This commit was to move the board_nand_init() function from NAND driver to board.c file. This allow customization of board_nand_init() function.
