test: dm: clk_ccf: test ccf_clk_ops

Browse Source 
Assign ccf_clk_ops to .ops of clk_ccf driver so that it can act as an
clk provider. Also add "#clock-cells=<1>" to its device tree node.

Add "i2c_root" to clk_test in the device tree and driver for testing.

Get "i2c_root" clock in CCF unit tests and add tests for it.
