cxl: Workaround malformed pcie packets on some cards

This works around a pcie host bridge defect on some cards, that can cause
malformed Transaction Layer Packet (TLP) errors to be erroneously reported.

The upper nibble of the vendor section PSL revision is used to distinguish
between different cards. The affected ones have it set to 0.
