Subject: [PATCH 1/2] mtd: spinand: macronix: Add support for MX31LF1GE4BC

The Macronix MX31LF1GE4BC is a 3V, 1Gbit (128MB) serial
NAND flash device.

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