[PATCH V1 3/3] ASoC: fsl: fsl-asoc-card: Select SND_SOC_IMX_AUDMUX

Building kernel with SND_SOC_IMX_AUDMUX=n leads to the following error:

   sound/built-in.o: In function `fsl_asoc_card_probe':

quoted

fsl-asoc-card.c:(.text+0x1467b5): undefined reference to `imx_audmux_v2_configure_port'
fsl-asoc-card.c:(.text+0x1467d0): undefined reference to `imx_audmux_v2_configure_port'
fsl-asoc-card.c:(.text+0x1467ed): undefined reference to `imx_audmux_v2_configure_port'
fsl-asoc-card.c:(.text+0x146807): undefined reference to `imx_audmux_v2_configure_port'

Update Kconfig to select SND_SOC_IMX_AUDMUX when SND_SOC_FSL_ASOC_CARD=y.
