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.

This enables support for the Quad SPI controller in master mode.
We only connect the NOR to this controller now.
