[RFC 4/4] mtd: spinand: macronix: Add support for MX35LF2GE4AD

[Zhengxun]

Macronix NAND Flash devices are available in
different configurations and densities.

MX"35" means SPI NAND
MX35"LF"/"UF" , LF means 3V and UF meands 1.8V
MX35LF"2G" , 2G means 2Gbits
MX35LF2G"E4"/"24"/"14",
E4 means internal ECC and Quad I/O(x4)
24 means 8-bit ecc requirement and Quad I/O(x4)
14 means 4-bit ecc requirement and Quad I/O(x4

Validated by read, erase, write, on Xilinx Zynq
PicoZed FPGA board which included Macronix SPI
Host (drivers/spi/spi-mxic.c).
