mtd: zynq: nand: Move board_nand_init() function to board.c

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.
