[PATCH 5.18 156/181] arm64: dts: ti: k3-j721s2: Fix overlapping GICD memory region

[Greg Kroah-Hartman]

From: Matt Ranostay <mranostay@xxxxxx>

commit 856216b70a41ff3f8c866b627546afa01567b389 upstream.

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@100000/interrupt-controller@1800000: couldn't map region 0
