Subject: [PATCH 01/19] media: i2c: ov4689: Clean up and annotate the register table
Many values in the register table are actually power-on
defaults. Remove those and also unused HDR exposures and gains.
Annotate the remaining values using the publicly available datasheet
to facilitate further development. No functional change intended.
