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
