This allows using raw PCIe mapped BAR4 resources for management. MSI interrupts are not supported.
Even when using a module that does not support UIO, management engine can still be used.

Usage example under fm_platform_attributes.cfg

api.platform.config.switch.0.resource4DevName text /sys/bus/pci/devices/0000:84:00.0/resource4

Should work under containers and links, given the actual device is the target and not the resource.
