arm64: PCI: Search ACPI namespace to ensure ECAM space is reserved
The static MCFG table tells us the base of ECAM space, but it does not
reserve the space -- the reservation should be done via a device in the
ACPI namespace whose _CRS includes the ECAM region.
Use acpi_resource_consumer() to check whether the ECAM space is reserved by
an ACPI namespace device. If it is, emit a message showing which device
reserves it. If not, emit a "[Firmware Bug]" warning.
