The current sh_mobile_ceu_camera driver can cause an Oops, if a CSI2 and a
parallel camera are registered on the same CEU. Fix it by making CSI2
association with a camera more targeted.

G_CROP, S_CROP, CROPCAP, G_FMT, and S_FMT functionality in the mt9t112
driver was broken on many occasions. This patch allows consistent
cropping for rectangles also larger than VGA and cleans up multiple
other issues in this area. It still doesn't add support for proper
scaling, using the sensor own scaler, so input window is still
always equal to the output frame.

With the new subdevice media-bus configuration methods bus-width is not
configured along with other bus parameters, instead, it is derived from
the data format. With those methods it is convenient to specify
supported bus-widths in the platform data as (1 << (width - 1)). We
redefine SOCAM_DATAWIDTH_* flags to use the same convention to make
platform data seemlessly reusable.
