5d07163334 platform:x86 decouple telemetry driver from the optional IPC resources 
Currently the optional IPC resources prevent telemetry driver from
probing if these resources are not in ACPI table. This patch decouples
telemetry driver from these optional resources, so that telemetry driver
has dependency only on the necessary ACPI resources.
