c008280a9a spi: f-ospi: Add missing spi_mem_default_supports_op() helper
The .supports_op() callback function returns true by default after
performing driver-specific checks. Therefore the driver cannot apply
the buswidth in devicetree.

Call spi_mem_default_supports_op() helper to handle the buswidth
in devicetree.

358f803ae2 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.
