Currently, the hardware is not given a complete initial
configuration.

In order to fix this, this rather large commit reworks
standard, frame format and input configuration. While
at it, we introduce proper functions to configure
each parameter, and as a result the code is a bit cleaner.

This define is a duplicate of V4L2_YCBCR_ENC_601. So mark it as
'should not be used' and put it under #ifndef __KERNEL__ to
prevent drivers from referring to it.

The SYCC Y'CbCr encoding is identical to the 601 encoding. Since the
SYCC define is about to be removed for use in the kernel we need to
drop it in the TPG code as well.

This patch also adds a 4th decimal to the 601 conversion matrix.
That was specified by the sYCC spec and it makes sense to use this
across the board.

The functionality that was part of the tw686x-kh driver but not of the
mainlined tw686x driver has now been added to the tw686x driver as well.

So this driver no longer adds any functionality not available through
the mainlined driver and it can now be removed.
