spi: f_ospi: Add missing spi_mem_default_supports_op() helper
[ Upstream commit bc43c5ec1a97772269785d19f62d32c91ac5fc36 ]
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.
