media: ov5670: Fix incorrect frame timing reported to user Previously, pixel-rate/(pixels-per-line * lines-per-frame) was yielding incorrect frame timing for the user. OV sensor is using internal timing and this requires conversion (internal timing -> PPL) for correct HBLANK calculation. Now, change pixels-per-line domain from internal sensor clock to pixels domain. Set HBLANK read-only because fixed PPL is used for all resolutions. And, use more accurate link-frequency 422.4MHz instead of rounding down to 420MHz.

[media] media: ov5670: Use recommended black level and output bias Previously, images were relatively darker due to non-optimal settings for black target level and bias. Now, use recommended settings for black target level and output bias as default values. The same default settings apply to all the resolutions. Given these recommeneded settings do not change dynamically, add these to existing mode register settings.

media: i2c: Fix pm_runtime_get_if_in_use() usage in sensor drivers pm_runtime_get_if_in_use() returns -EINVAL if runtime PM is disabled. This should not be considered an error. Generally the driver has enabled runtime PM already so getting this error due to runtime PM being disabled will not happen. Instead of checking for lesser or equal to zero, check for zero only. Address this for drivers where this pattern exists.
