ipq40xx: add support for Macronix MX35LF1GE4AB SPI NAND
Without a proper SPI NAND support (SPI NAND framework is available in kernel >= 4.19) the only way to make such flash working is to include it in raw/parallel NAND subsystem support and combine with mt29f staging driver. Obviously, this approach isn't going to be accepted by upstream (similar support for Winbond W25N01GV was rejected). Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>
