Subject: [PATCH 10/16] arm64: dts: qcom: sc8280xp: 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 addresses
(0x30200000, 0x32200000, 0x34200000, 0x38200000, 0x3c200000) specified in
the ranges property for I/O region.

Fixes: 813e83157001 ("arm64: dts: qcom: sc8280xp/sa8540p: add PCIe2-4 nodes")
Reported-by: Arnd Bergmann <arnd@...db.de>
