ASoC: max98090: remove 24-bit format support if RJ is 0
[ Upstream commit 5628c8979642a076f91ee86c3bae5ad251639af0 ]
The supported formats are S16_LE and S24_LE now. However, by datasheet
of max98090, S24_LE is only supported when it is in the right justified
mode. We should remove 24-bit format if it is not in that mode to avoid
triggering error.
