Add a driver for Macronix raw NAND controller. This patch referred from linux mxic_nand.c. The difference from the linux version is described here. 1. In order to adapt to the uboot nand framework, add function binding (cmdfunc, read_byte, read_buf, write_buf). 2. Added parsing command format to use hardware correctly. 3. Remove the incompatible functions of Uboot. Signed-off-by: Zhengxun Li <zhengxunli@mxic.com.tw>
