[PATCH v2] arm64: dts: ti: k3-j721s2: fix overlapping GICD memory region

[Matt Ranostay]

GICD region was overlapping with GICR causing the latter to not map
successfully, and in turn the gic-v3 driver would fail to initialize.

This issue was hidden till commit 2b2cd74a06c3 ("irqchip/gic-v3: Claim iomem resources")
replaced of_iomap() calls with of_io_request_and_map() that internally
called request_mem_region().

Respective console output before this patchset:

[    0.000000] GICv3: /bus at 100000/interrupt-controller at 1800000: couldn't map region 0
