This patch simply adds support for PCI devices.
Reviewed-by: Dmitry Osipenko
Tested-by: Dmitry Osipenko

Changelog
v6->v7
* Renamed goto labels, suggested by Thierry.
v5->v6
* Added Dmitry's Reviewed-by and Tested-by.
v4->v5
* Added Dmitry's Reviewed-by
In tegra_smmu_(de)attach_dev() functions, we poll DTB for each
client's iommus property to get swgroup ID in order to prepare
"as" and enable smmu. Actually tegra_smmu_configure() prepared
an fwspec for each client, and added to the fwspec all swgroup
IDs of client DT node in DTB.
So this patch
This series is to add PCI support in tegra-smmu driver.
Changelog (Detail in each patch)
v6->v7
* Added comments for put_device in PATCH-2
* Renamed goto labels in PATCH-3
* Kept Dmitry's Reviewed-by and Tested-by as no function change
v5->v6
* Dropped a NULL check, per Dmitry's comments
*
The bus_set_iommu() in tegra_smmu_probe() enumerates all clients
to call in tegra_smmu_probe_device() where each client searches
its DT node for smmu pointer and swgroup ID, so as to configure
an fwspec. But this requires a valid smmu pointer even before mc
and smmu drivers are probed. So in
