media: ov2740: Fix hts value
HTS must be more then width, so the 1080 value clearly is wrong,
this is then corrected with some weird math dividing clocks in
to_pixels_per_line() which results in the hts getting multiplied by 2,
resulting in 2160.
Instead just directly set hts to the correct value of 2160 and
drop to_pixels_per_line().
