Subject: [PATCH v3 7/7] arm64: dts: freescale: add initial device tree for TQMa8Mx with i.MX8M

This adds support for TQMa8Mx module on MBa8Mx board.

Signed-off-by: Alexander Stein <alexander.stein@...tq-group.com>
---
Changes in v3:
* Fixed name for audio-codec
* Use matrix instead of array for 'fsl,pins'
* Removed TODO regarding unsupported USB over-current polarity

Changes in v2:
* Renamed codec -> audio_codec
* Moved VPU enable from MB+SOM DT to SOM DT
* Fixed pinctrl node names
* Removed empty chosen node
* Removed regulator-always-on on non-switchable regulators
* Enable GPU node
* Add "fixed-clock" subnode for pcf85063
  See commit 4c8a7b80d5f3 ("rtc: pcf85063: add support for fixed clock")
