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).
