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).
