imx8mp d18/levy: add support for TAS2505 audio-codec on ModularVision

This patch adds the necessary device-tree settings for the ModularVision
carrier board to support the TAS2505 audio-codec.

Note: Also requires CONFIG_SND_SOC_TLV320AIC32X4_I2C to be enabled in
kernel defconfig (the tlva320aic32x4 driver also provides support for
the TAS2505 codec).
