    xen/arm: platform: Select GICV3 dependency for RCAR4
    
    The Renesas R-Car Gen4 platform requires the GICv3 driver,
    including support for the Interrupt Translation Service (ITS).
    
    Without explicitly selecting GICV3, it was possible to create a
    configuration with RCAR4=y and GICV3=n, leading to a build failure
    due to unmet dependencies.
    
    GICv3 driver (GICV3) [Y/n/?] (NEW) n
    WARNING: unmet direct dependencies detected for HAS_ITS
      Depends on [n]: GICV3 [=n] && !NEW_VGIC [=n] && !ARM_32 [=n]
      Selected by [y]:
      - RCAR4 [=y] && <choice> && ARM_64 [=y]

    Fix this by adding "select GICV3" to the RCAR4 Kconfig entry.
