msm: smd_pkt: Verify edge during probe operation

Verify that both the platform id (SMD port edge) and the platform name
(SMD port name) match during driver binding to prevent registering for
the correct SMD port name, but the wrong SMD port edge.

An SMD Port can be uniquely identified in the system by its name and
edge and both of these must match for binding to ensure that the correct
port is being opened.  Without this check, the driver could potentially
attach to the wrong processor resulting in undefined behavior.
