[edk2-devel] [PATCH 2/2] DynamicTablesPkg: AcpiSsdtPcieLibArm: Use QWord to describe I/O range

["Jeff Brasen via groups.io" <jbrasen=nvidia.com@groups.io>]

From: Vidya Sagar <vidyas@nvidia.com>

Use AmlCodeGenRdQWordIo() to generate the I/O range in _CRS instead of
AmlCodeGenRdDWordIo() to cater to the scenarios where 64-bit addresses
can be used to generate I/O packets over the PCIe bus.
