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.

In particular: - 8bpp modes: high resolution sizes (>= 1280x720) - 16bpp modes: all sizes - 24bpp modes: low resolutions sizes (< 1280x720) Restrict the frame sizes enumerations to the above constraints. While at it, make sure the fse->mbus_code parameter is valid, and return -EINVAL if it's not.
