spi: renesas,sh-msiof: Miscellaneous improvements

Browse Source 
Make "clocks" and "power-domains" required everywhere.
Make "resets" required on R-Car Gen2 and newer (i.e. all but SH-Mobile).

Update the example to match reality:
  - Use interrupt binding definitions instead of hardcoded numbers,
  - Convert to new-style CPG/MSSR bindings,
  - Add missing "power-domains" and "resets" properties.
