spi: Add a driver for the Freescale/NXP QuadSPI controller
This driver is derived from the SPI NOR driver at mtd/spi-nor/fsl-quadspi.c. It uses the new SPI memory interface of the SPI framework to issue flash memory operations to up to four connected flash chips (2 buses with 2 CS each). The controller does not support generic SPI messages. This patch also disables the build of the "old" driver and reuses its Kconfig option CONFIG_SPI_FSL_QUADSPI to replace it.
