mtd: spi-nor: add driver for NXP SPI Flash Interface (SPIFI)
Add SPI-NOR driver for the SPI Flash Interface (SPIFI)
controller that is found on newer NXP MCU devices.
The controller supports serial SPI Flash devices with 1-, 2-
and 4-bit width in either SPI mode 0 or 3. The controller
can operate in either command or memory mode. In memory mode
the Flash is exposed as normal memory and can be directly
accessed by the CPU.
