ARM: shmobile: r8a7778 dtsi: Improve and correct HSPI nodes

  - Add "renesas,hspi-r8a7778" compatible value,
  - Correct reference to parent interrupt controller
    (use "interrupt-parent" instead of "interrupt-controller"),
  - Add missing "#address-cells" and "#size-cells" properties, which are
    needed when populating the SPI buses.
