cppcheck complains about potential null pointer dereference but it's
rather an unnecessary assignment to NULL before walking through a
list.

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.

After carefully checking, it appears that both tdmout and tdmin require the
rising edge of the sclk they get to be synchronized with the frame sync
event (which should be a rising edge of lrclk).
TDMIN was improperly set before this patch. Remove the sclk_invert quirk
which is no longer needed and fix the sclk phase.

After carefully checking the result provided by the TDMIN on the g12a and
sm1 SoC families, the TDMIN skew offset appears to be 3 instead of 2 on the
axg.

The TDMIN component, as it, has a maximum of 16 input. Depending on
the SoC, these may not all be connected.
Instead of decribing only the connected inputs of each SoC, describe
them all and let ASoC routing do the rest.

The g12a tdmout requires a different signal skew offset than the axg.
With this change, the skew offset is added as a parameter of the tdm
formatters to prepare the addition of the g12a support.
