arm64: dts: rockchip: fixes the gic400 2nd region size for rk3368

commit ad1cfdf518976447e6b0d31517bad4e3ebbce6bb upstream.

The 2nd additional region is the GIC virtual cpu interface register
base and size.

As the gic400 of rk3368 says, the cpu interface register map as below

:

-0x0000 GICC_CTRL
.
.
.
-0x00fc GICC_IIDR
-0x1000 GICC_IDR

Obviously, the region size should be greater than 0x1000.
So we should make sure to include the GICC_IDR since the kernel will access
it in some cases.
