Hao Yao 56fa9206d3 media: i2c: ov13b10: Fix h_blank calculation
Pixel per line (PPL) is calculated as pixel_rate / (VTS * FPS), which
is not decided by MIPI CSI-2 link frequency. PPL can vary while link
frequency keeps the same. If PPL is wrong, the h_blank = PPL - width
is also wrong then FPS control is inaccurate.

This patch fix h_blank by:
1. Move PPL from link_freq_config to ov13b10_mode
2. Add PPL value for different modes
3. Use PPL from mode to calculate h_blank

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 reStructuredText 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.
