interconnect: qcom: icc-rpmh: Add support for enabling BCMs needed for QoS

Browse Source 
Some QoS blocks require voting for BCMs before their registers can be
accessed, since they require clocks and regulators controlled by BCM.
Hence add qos_proxy flag to indicate the BCM needs to be voted for
QoS configuration.
