Subject: [PATCH 03/16] arm64: dts: qcom: sc7280: Fix the PCI I/O port range

For 1MiB of the I/O region, the I/O ports of the legacy PCI devices are
located in the range of 0x0 to 0x100000. Hence, fix the bogus PCI address
(0x40200000) specified in the ranges property for I/O region.

Fixes: 92e0ee9f83b3 ("arm64: dts: qcom: sc7280: Add PCIe and PHY related nodes")
