spi: sh-msiof: Improve bindings
Documentation:
- Add missing "interrupt-parent", "#address-cells", "#size-cells", and
"clocks" properties,
- Add missing default values for "num-cs", "renesas,tx-fifo-size" and
"renesas,rx-fifo-size",
- Add a reference to the pinctrl documentation.
Implementation:
- As "num-cs" is marked optional, provide a sensible default.
