ASoC: sun4i-spdif: Add clock multiplier settings

[ Upstream commit 0a231930 ]

There have been intermittent issues with the SPDIF output on H3
and H2+ devices which has been fixed by setting the s_clk to 4
times the audio pll.
Add a quirk for the clock multiplier as not every supported SoC
requires it. Without the multiplier, the audio at normal sampling
rates was distorted and did not play at higher sampling rates.
