[0/2] cxl: Fixup Legacy DVSEC Init failures

Message

Krzysztof reports a case where a timeout waiting for the "memory info
valid" indication in the DVSEC range register also resulted in the PCI
driver failing to load. Fix that by making DVSEC range register probe
failures non-fatal.

While investigating that came across the error message to validate EFI
memory map publication of DVSEC range registers and could not determine
that it affords any safety or actionable fixes to report back to a BIOS
vendor.
