This patch set contains proposed API changes to the pci uclass for multi PCIe host controller platforms.
1. Add changes to fix bus number of a host bridge
Differentiate bus numbers hierarchy for root bridges. All bus numbers are device sequence numbers minus root bridge sequence number. This way, every root bridge and its downstream EPs bus numbers start from 0. Thus, root bridges are different hierarchy of bus numbers.
2. Get next device fail with driver probe fail
In Multi PCIe host controller platforms, if one PCIe host driver probe fails for any reason, the next PCIe host controller device pointer should be tried with its driver probe. Instead, currently the code simply stops enumeration. Add the feature described above.
3. Add ability to parse dma-regions given in PCIe host controller's DT node.
