mtd: spi-nor: macronix: Add support for mx66u2g45g
The Macronix mx66u2g45g is a 1.8V, 2Gbit (256MB) device that
supports x1, x2, or x4 operation.
Tested on Pensando SoC hardware with a cadence quadspi controller
via drivers/spi/spi-cadence-quadspi.c, in x2 mode at 50MHz.
- random data write, erase, read - verified erase operations
- random data write, read/compare - verified write/read operations
