[PATCH 07/16] media: iris: Add platform flag for instantaneous bandwidth voting

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

From: Dikshita Agarwal <dikshita.agarwal@oss.qualcomm.com>

AR50LT require explicit instantaneous bandwidth (IB) voting in addition
to average bandwidth (AB) when configuring interconnect QoS. This
requirement is due to QSB (Qualcomm System Bus) 128b to
QNS ( Qualcomm Network Switch) 256b conversion at video noc in AR50LT
which is not needed for other IRIS cores.

In preparation of adding support for AR50LT core, introduce
platform-configurable IB multiplier and enable IB voting for all SoCs.
Existing platforms default to IB == AB, while AR50LT requires 2x peak
bandwidth.
