b9da5086b8 dm: x86: baytrail: Correct PCI region 3 when driver model is used
Commit afbbd413a fixed this for non-driver-model. Make sure that the driver
model code handles this also.

5afeb4bb45 dm: pci: Correct bus number when scanning sub-buses
The sub-bus passed to pciauto_prescan_setup_bridge() is incorrect. Fix it
so that sub-buses are numbered correctly.

aec241dfb4 dm: pci: Use the correct hose when configuring devices
Only the PCI controller has access to the PCI region information. Make sure
to use the controller (rather than any attached bridges) when configuring
devices.

This corrects a failure to scan and configure devices when driver model is
enabled for PCI.

Also add a comment to explain the problem.

2bb02e4fe2 dm: pci: Allow PCI bus numbering aliases
Commit 9cc36a2 'dm: core: Add a flag to control sequence numbering' changed
the default uclass behaviour to not support bus numbering. This is incorrect
for PCI and that commit should have enabled the flag for PCI.

Enable it so that PCI buses can be found and the 'pci' command works again.
Also add a test for this.

ff3e077bd2 dm: pci: Add a uclass for PCI
Add a uclass for PCI controllers and a generic one for PCI devices. Adjust
the 'pci' command and the existing PCI support to work with this new uclass.
Keep most of the compatibility code in a separate file so that it can be
removed one day.

TODO: Add more header file comments to the new parts of pci.h
