Subject: [148/152] [media] mx2_camera: fix pixel clock polarity configuration

2.6.36-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Baruch Siach <baruch@...s.co.il>

commit 42cc37fe20cc680fb58fe12ae5ba718d683b8ca2 upstream.

When SOCAM_PCLK_SAMPLE_FALLING, just leave CSICR1_REDGE unset, otherwise we get
the inverted behaviour.
