MediaTek ARM64 DeviceTree updates

This adds a couple of fixes and improvements for multiple
MediaTek SoCs.

In particular:
- Indentation/whitespace fixes for some devicetrees
- Documentation improvements for MediaTek Mute-X
- dtbs-check warnings fixes
  - MT8390 Tungsten boards: removal of unnecessary cells
  - MT6795 SoC: removal of deprecated property in UART DMA
- MT6359 PMIC's RTC now uses the correct compatible string
- MT8183/86/88/92/95 SoCs gain support for the UART DMA IPs
- MT8186 gets a new CCI OPP table to resolve lockups
- MT8188/83 Chromebooks now got the correct SPI NOR supply
- MT8192 Asurada drops support for the (unused) MMC1 port
- MediaTek Genio 510/700/1200 EVKs and Radxa NIO-12L now get
  their PMIC power input tree completed with assignment of
  the correct supplies

-  Mediatek mutex, namely MUTEX, is used to send the triggers signals called
-  Start Of Frame (SOF) / End Of Frame (EOF) to each sub-modules on the display
-  data path or MDP data path.
-  In some SoC, such as mt2701, MUTEX could be a hardware mutex which protects
-  the shadow register.
+description:
+  MediaTek Mute-X, namely MUTEX, is used to "mute" or "unmute" trigger signals
+  like Start Of Frame (SOF), End Of Frame (EOF), Tearing Effect (TE / VSYNC)
+  and others to each hardware sub-modules in the Display Controller IP or in
+  the Media Data Path (MDP) IP.
+  In some SoCs like MT2701, this hardware module may feature functionality
+  to, for example, protect shadow registers by blocking auto write triggers
+  upon operation (usually frame push) completion.
   MUTEX device node must be siblings to the central MMSYS_CONFIG node.
   For a description of the MMSYS_CONFIG binding, see
