Subject:[OMAPZOOM][PATCH 0/3] ISP: Component order

The RAW10 component order for all three sensors I test with (MT9P012, OV3640 & 
IMX046) is different.  This patch set uses different horz/vert offsets in CCDC 
so that the output RAW component order is the same for all sensors.

Currently sph and slv in the board file (for MT & OV) are used to fix component 
order in Previewer. However this approach doesn't work for the Sony IMX046 
sensor.
This patch causes the component order output of CCDC to be the same for all 
sensors.  Since the order is the same going into Previewer this means that there 
is not need for sph and slv to change per sensor.

                     woffset    hoffset      RAW10 test     YUV test
MT9P012    GR..BG      1          0            OK             OK

OV3640     BG..GR      1          1            OK             OK

Patch:
1/3  Removes original bug introduced with IMX046 patch.
2/3  Changes in CCDC to all easy setup of component order in board file.
3/3  Remove no longer needed prev_sph & prev_slv from boad file.
