interconnect: icc-clk: Specify master/slave ids
Presently, icc-clk driver autogenerates the master and slave ids.
However, devices with multiple nodes on the interconnect could
have other constraints and may not match with the auto generated
node ids.
Hence, modify the driver to use the master/slave ids provided by
the caller instead of auto generating.
Also, update clk-cbf-8996 accordingly.
