Subject: [PATCH] ASoC: meson: axg-tdmin: fix axg skew offset

The signal captured on from tdm decoder of the AXG SoC is incorrect. It
appears amplified. The skew offset of the decoder is wrong.

Setting the skew offset to 3, like the g12 and sm1 SoCs, solves and gives
correct data.

Fixes: 13a22e6a98f8 ("ASoC: meson: add tdm input driver")
