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
