If we don't set IMX_AUDMUX_V2_PTCR_TCLKDIR in the AUDMUX PTCR
register (means Tx clock pin is input), we don't need to set
IMX_AUDMUX_V2_PTCR_TCSEL as well. Since both i.MX35, i.MX51 and
i.MX6 datasheet says "When Tx clock pin set as an input, the TCSEL
settings are ignored".

snd_soc_dapm_put_volsw() sets connect incorrectly in the case max > 1 with
invert. In that case, the raw disconnect value should be max, which corresponds
to the userspace value 0.

SOC_DAPM_SINGLE() or SOC_DAPM_SINGLE_TLV() elsewhere or in the future.

There is only one caller and this allows us to cleanly leave the CODEC
