dm: test: clk: add the test for the ccf gated clock

Unlike the other clock types, in the case of the gated clock, a new
driver has been developed which does not use the registering routine
provided by the common clock framework.
The addition of the ecspi0 clock to sandbox therefore allows testing
the ccf gate clock.
