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.

On imx27_3ds board with ov2640 sensor:
ov2640 0-0030: ov2640 Product ID 26:42 Manufacturer ID 7f:a2
mx2-camera mx2-camera.0: MX2 Camera (CSI) driver probed, clock frequency: 44333333

On clone imx27_3ds board with mt9v111 sensor (draft driver):
mt9v111 0-0048: Detected a MT9V111 chip ID 823a
mx2-camera mx2-camera.0: MX2 Camera (CSI) driver probed, clock frequency: 44333333
