During the clock conversion for mx27 the "per4_gate" clock was missed to get
registered as a dependency of mx2-camera driver.
In the old mx27 clock driver we used to have:
DEFINE_CLOCK1(csi_clk, 0, NULL, 0, parent, &csi_clk1, &per4_clk);
,so does the same in the new clock driver.

I only test detection at kernel boot not streaming using Gstreamer due
to lack of time.
