[PATCH 4/6] ASoC: imx-mc13783: Remove unused driver

[Fabio Estevam <festevam@gmail.com>]

The imx-mc13783 was used on imx27-pdk and imx31-pdk non-DT platforms.

Since 5.10-rc1, i.MX has been converted to a DT-only platform and all
board files are gone.

Remove the imx-mc13783 audio machine driver as there is no user at all.
