To each libcamera PixelFormat two V4L2 formats are associated, the 'single' and 'multi' format variants. The two versions list plane contiguous and non-contiguous format variants, and an optional argument to V4L2PixelFormat::fromPixelFormat() was used to select which one to pick. In order to prepare to remove V4L2PixelFormat::fromPixelFormat(), and considering that no caller in the codebase uses the non-contiguous format variant, merge the two formats vectors in a single one and default the selection to the first available one, which is functionally equivalent to what is currently implemented.
