Previously, the sensor was not streaming after resume from suspend,
i.e. on S0->S3->S0 transition. Due to this, camera app preview appeared
as stuck.
Now, handle streaming state correctly in case of suspend-resume.

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.

Previously, vblank range given to user was too big, falling outside
of permissible range for a given resolution. Sometimes, too low vblank
resulted in errors.
Now, limit vblank to only permissible range for a given resolution.
This change limits lower-bounds of vblank, doesn't affect upper bounds.

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.
