There was some rather odd spacing in a few of the ite8709-specific
functions that made it hard to read those sections of code. This is just
a simple reformatting.

Just recently acquired an Asus Eee Box PC with an onboard IR receiver
driven by ite-cir (ITE8713 sub-variant). Works out of the box with the
ite-cir driver in 2.6.39, but stops working after a suspend/resume
cycle. Its fixed by simply reinitializing registers after resume,
similar to what's done in the nuvoton-cir driver. I've not tested with
any other ITE variant, but code inspection suggests this should be safe
on all variants.

Recently mediabus pixel format codes have become a part of the user-
space API, at which time their values also have been changed from
contiguous numbers, running from 0 to sparse numbers with values
around 0x1000, 0x2000, 0x3000... This made them unsuitable for the
use as array indices. This patch switches soc-camera internal format
look-ups to not depend on values of those macros.

The initial version of this patch (commit
d5976931639176bb6777755d96b9f8d959f79e9e) had some issues:
* It didn't correctly calculate the size of the YUV buffer for 4:2:2,
resulting in capture sometimes being offset by 1/3rd of a picture.
* There were a lot of variables duplicating information the driver
already knew, which have been removed.
* There was an in-kernel format conversion - libv4l can do this one,
and is the right place to do format conversions anyway.
* Some magic numbers weren't properly explained.
Fix all these issues, leaving just the move from videobuf to videobuf2
to do.
