Enable GIC ITS support on Rockchip RK3566/RK3568 SoCs by adding
necessary GIC erratum workarounds and moving RK356x PCIe MSI to use
ITS instead of MBI.

Changelog:

v2: - Changed Kconfig and commit descriptions of the GIC driver patch,
      as was requested by Marc Zyngier.

    - Added ack from Marc Zyngier to the GIC driver patch.

    - Squashed DT patch that added dma-noncoherent property to GIC node
      into the patch that adds MSI controller node, as was suggested by
      Marc Zyngier.
