The allwinner kernel has a third option where the horizontal phase of the second channel will be set to a different value than the vertical one (and seems like it's the same value than one used on the first channel). However, that code path seems to never be taken, so we can ignore it for now, and it's essentially what we're doing so far as well. Since we will have always the same values across each components of the filter setup for a given channel, we can simplify a bit our frontend structure by only storing the phase value we want to apply to a given channel.
