[PATCH 1/6] ARM: shmobile: r7s72100 dtsi: Use "arm,pl390" for GIC

Replace the "arm,cortex-a9-gic" compatible value for the GIC by
"arm,pl390", as the documentation states it is a PL390.
This has been confirmed (thanks Chris, Wolfram!) by reading the
GICD_IIDR register, which reports 0x0000043b (PL390 = 0x00, ARM =
0x43b).
This has no effect on runtime behavior, as currently the GIC driver
treats both compatible values the same.
