clk: disable clk gate tests for s390

Currently clk-gate tests for s390 fail as the tests create a pretend
clk-gate and use a "fake_reg" to emulate the expected behavior of the
clk_gate->reg. I added some debug statements to the driver and noticed
that the reg changes after initialization to -1, which is coming from an
error coming from zpci_load(). This is likely because the test is using
fake iomem and the s390 architecture likely isn't designed to handle
that. Turn off the clk-gate tests for s390 for now as there is no clear
work around for this problem as discussed in upstream conversation [1].
