misc: mic: Add support for kernel mode SCIF clients
Add support for registration/de-registration of kernel mode SCIF
clients. SCIF clients are probed with new and existing SCIF peer
devices. Similarly the client remove method is called when SCIF
peer devices are removed.
Changes to SCIF peer device framework necessitated by supporting
kernel mode SCIF clients are also included in this patch.
