Bug description:
[SRU Justification]
[Impact]
Current linux-bluefield kernel reports that PCI BARs larger than 128GB
are disabled.
Increase the maximum PCI BAR size from 128GB to 8TB for future
expansion.
[Test Plan]
Use updated kernel with PCI device with PCI BARs larger than 128GB.
[Where problems could occur]
No potential problems are expected.
[Other Info]
Testing has been provided by the customer. This patch is a cherry-pick
from the upstream 5.18 kernel. It is intended for linux-bluefield
kernel re-spin but it may be also suitable for the generic kernel
(separate submission).
