[PATCH 0/5] Add AMD Versal CPM/QDMA PCIe support

This series adds PCIe root port support for the AMD Versal CPM4, CPM5
and QDMA PL (soft IP) host bridges, and enables it along with NVMe
storage on the xilinx_versal_virt platform.

Patch 1 adds a generic mmap config-space write helper for host bridges
that only decode 32-bit accesses.
Patches 2 and 3 add the QDMA PL and CPM4/CPM5 host bridge drivers,
respectively.
Patch 4 maps the CPM5 ECAM windows as device memory so config space
accesses are not cached or reordered.
Patch 5 wires everything up in the versal_virt defconfig and adds NVMe
as a distro boot target.
