The ov2680_720p_30fps register init list used for the 1296x736 resolution sets the hsize register to 1296 and the vsize register to 736. This is actually the right thing to do when combined with the atomISP2 because the ISP requires 16 bytes padding leaving userspace to see 1280x720. But the resolution list entries for this was incorrectly reporting the resolution being send to the ISP as already being 1280x720, leaving usespace to see 1274x704 as resolution. Worse then userspace seeing a weird resolution selecting the 1280x720 sensor resolution (which in reality is sending 1296x736) to the ISP was causing the ISP to hang on Cherry Trail based tablets (Bay Trail works fine for some reason). This commit also adds a bunch of comments annotating what the various register writes the init lists are doing.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
