Fix PIO read_byte() implementation not only used for the legacy READ ID but also the PARAM command required for proper ONFI detection. This fix is inspired by Lucas Stach's Linux Tegra NAND driver of late (not mainline yet but getting there soon I hope). I vaguely remember that those commands are special on 16-bit bus NAND (e.g. always return 8-bit data regardless) and later Linux MTD fixed/ changed the way this is handled which in turn broke once U-Boot pulled that in. Basically instead of doing PIO read regular DMA block read is now used which this patch actually fixes.
