oxnas: clean-up NAND driver to fix probing issue
A re-write of the driver based on xway_nand.c and constants as well as the cmd_ctrl() function from the original oxnas_nand.c resulted in a extremely similar looking file (see diffsize), and fixes the issue of NAND not being detected on newer kernels.
