[PATCH 2/4] interconnect: qcom: rpm: Set QoS parameters regardless of RPM bw setting

[Konrad Dybcio]

QoS parameters and RPM bandwidth requests are wholly separate. Setting one
should only depend on the description of the interconnect node and not
whether the other is present. If we vote through RPM, QoS parameters
should be set so that the bus controller can make better decisions.
If we don't vote through RPM, QoS parameters should be set regardless,
as we're requesting additional bandwidth by setting the interconnect
clock rates.

The Fixes tag references the commit in which this logic was added, it
has since been shuffled around to a different file, but it's the one
where it originates from.
