89d8b615f2 media: ov13858: Correct link-frequency and pixel-rate 
Previously both link-frequency and pixel-rate reported by
the sensor was incorrect, resulting in incorrect FPS.
Report link-frequency in Hz rather than link data rate in bps.
Calculate pixel-rate from link-frequency.

33eea13263 media: ov13858: Fix initial expsoure max 
Previously, initial exposure max was set incorrectly to (0x7fff - 8).
Now, limit exposure max to current resolution (VTS - 8).

b3775edc66 media: ov13858: Set default fps as current fps 
On format change, sometimes, sensor was streaming at a much higher
FPS than the default. This was resulting in various problems like
frame drops/corruption.

Upon format change, set default vblank as current vblank. This will
ensure that sensor will start streaming at default fps.
