When enumerating bridges, the allocated memory base and limit must be
programmed in the bridge config registers.
The base is programmed when starting enumerating the bridge and the
limit is programmed when all endpoints of the bridge and sub-bridges
are enumerated.
Add a second callback to get the base of the next allocation in
order to fill these base & limit values.

As suggested by Tomasz Bursztyka, it's clearer to move generic after the
domain prefix, here pcie.

As suggested by Tomasz Bursztyka, translate is clearer than xlate in
the PCIe controller functions and callbacks names.

This adds a generic PCIe Controller driver API providing the
necessary callbacks & config structure to handle the PCIe
config space and BAR regions handling.
