It's clearly a question of perspective: The way I see it, this
is not a driver at all, but a quirk for the acpi-pci driver,
and having hardware specific code shared between the two
complicates things.

In both cases (xgene and hisi), only a very small portion of
PCI host driver is needed as for the ACPI quirk, while all
of the hardware specific setup can be left to the firmware
