[PATCH v2 2/2] mtd: spi-nor: Support SPI_NOR_DUAL_READ on Micron mt25qu02g.

[David Clear]

The Micron mt25qu02g supports both x2 and x4 transactions.  Add the
SPI_NOR_DUAL_READ to its spi_nor_ids[] table entry.

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
