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, allow the driver to provide the preferred master
and slave ids.

Also, update clk-cbf-8996 accordingly.

v9: squash cbf-msm8996 change into this
v8: Per review feedback, set master/slave ids explicitly. Dont autogenerate
