[PATCH v5 6/7] arm64: dts: imx8mp: Add hdmi parallel audio interface node

[Shengjiu Wang <shengjiu.wang@nxp.com>]

The HDMI TX Parallel Audio Interface (HTX_PAI) is a bridge between the
Audio Subsystem to the HDMI TX Controller.

Shrink register map size of hdmi_pvi to avoid overlapped hdmi_pai device.
