After confirmed with Suravee, this patch set works OK on ARM64
hardware for PCI hostbridge init, and can enumerate PCI devices
(adding some ARM64 related PCI patches) and works fine with legacy
interrupt, so to me, this patch set is good to go :)

For this patchset:

Tested-by: Suravee Suthikulpanit <suravee.suthikulpanit@....com>

I will add my Reviewed-by for some of patches later.

Thanks
Hanjun
