[PATCH] Disable Clk-gate_tests for s390

[PATCH] Disable Clk-gate_tests for s390

[Audra Mitchell]

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].
