media: tvp5150: fix width alignment during set_selection()
[ Upstream commit bd24db04101f45a9c1d874fe21b0c7eab7bcadec ]
The driver ignored the width alignment which exists due to the UYVY
colorspace format. Fix the width alignment and make use of the the
provided v4l2 helper function to set the width, height and all
alignments in one.
