Renesas ARM Based SoC GIC Cleanup for v4.5

Browse Source 
On several Renesas ARM SoCs, the GIC is described in DT as being a
 Cortex A9 GIC, while it's actually a PL390. This is not only stated in
 the documentation, but has been verified by reading the GICD_IIDR
 register.
 
 To correct this:
   1. Update the DT compatible value to match reality,
   2. Update the board staging drivers to match the above.
