Rework the sensor modes sizes definition to: - Report the analog crop sizes - Report the visible crop size - Report the total pixels per line as HBLANK is fixed - Report the VBLANK value to make it programmable Also modify the ov5640_set_timings() function to program all the windowing registers are remove them from the per-mode register-value tables. Do not change the timing values from the ones reported in the register tables to maintain bisectability.
