The PFTF CM4 is an ACPI platform that isn't ECAM compliant. Its config

doesn't have an MCFG, and any MCFG provided would be nonsense
anyway. Instead, a Linux specific host bridge _DSD selects a custom
ECAM ops and cfgres. The cfg op picks between those two regions while
disallowing problematic accesses.

I do wonder if squashing patches 2 and 3 would make more sense,
otherwise we have a bcm2711_pcie_ops that is unused in patch 2.
