spi: Add Socionext F_OSPI SPI flash controller driver
Introduce Socionext F_OSPI controller driver. This controller is used to
communicate with slave devices such as SPI Flash memories. It supports
4 slave devices and up to 8-bit wide bus, but supports master mode only.
This driver uses spi-mem framework for SPI flash memory access, and
can only operate indirect access mode and single data rate mode.
