[PATCH 30/34] PR: Control iface support to trigger PR PASN Authentication

[Peddolla Harshavardhan Reddy <peddolla@xxxxxxxxxxxxxxxx>]

Changes to initiate PASN with Proximity Ranging negotiation.
Parameters to supplied with the command PR_PASN_START are
ranging role(ISTA/RSTA), ranging type(EDCA/NTB), frequency to
perform PASN on and such.
