Public bug reported:

[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).
