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.
