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.
