Driver for the i.MX2x CMOS Sensor Interface

This series contains a soc_camera driver for the i.MX25/i.MX27 CSI device, and
platform code for the i.MX25 and i.MX27 chips. This driver is based on a 
driver for i.MX27 CSI from Sascha Hauer, that  Alan Carvalho de Assis has 
posted in linux-media last December[1]. I tested the mx2_camera driver on the 
i.MX25 PDK. Sascha Hauer has tested a earlier version of this driver on an 
i.MX27 based board. I included in this version some fixes from Sascha that 
enable i.MX27 support.

Changes v1 -> v2
    Addressed the comments of Guennadi Liakhovetski except from the following:

    1. The mclk_get_divisor implementation, since I don't know what this code 
       is good for

    2. mx2_videobuf_release should not set pcdev->active on i.MX27, because 
       mx27_camera_frame_done needs this pointer

    3. In mx27_camera_emma_buf_init I don't know the meaning of those hard 
       coded magic numbers

    Applied i.MX27 fixes from Sascha.
