linux: Fix BUS_PLATFORM detection for non-PCI devices 

Commit 74b7427c41 (linux: Make platform device probe less fragile)
effectively dropped busid detection for non-PCI devices, for example on
OMAP we have "ID_PATH=platform-omapdrm.0". For such devices busid will not
be set, making platform probes (and server mediated fd support) impossible.

Fix that by extending config_udev_odev_setup_attribs() logic to support
platform devices as well.
