interconnect: qcom: Fix re-initializing the bcm

Browse source 
Currently, qcom_icc_bcm_init always assumes the bcm is not initialized.
There is a possibility that same bcm can belong to multiple providers
and re-initing the bcm adds the same bcm multiple times to the nodes
which are under the control of the bcm.
Hence add condition to check for bcm inited.
