This series adds dt-bindings and a driver for Socionext F_OSPI controller
for connecting an SPI Flash memory over up to 8-bit wide bus.
The controller supports up to 4 chip selects.

Changes since v1:
- Drop vendor-specific properties for devices from host dt-bindings
- Drop a function to parse vendor-specific properties
- Fix wrong maximum addr.bytes (5 to 4)
