c98e6e6836 arm64: dts: mt7622: fix BPI-R64 WPS button 
The bananapi R64 (BPI-R64) experiences wrong WPS button signals.
In OpenWrt pushing the WPS button while powering on the device will set
it to recovery mode. Currently, this also happens without any user
interaction. In particular, the wrong signals appear while booting the
device or restarting it, e.g. after doing a system upgrade. If the
device is in recovery mode the user needs to manually power cycle or
restart it.

The official BPI-R64 sources set the WPS button to GPIO_ACTIVE_LOW in
the device tree. This setting seems to suppress the unwanted WPS button
press signals. So this commit changes the button from GPIO_ACTIVE_HIGH to
GPIO_ACTIVE_LOW.

The official BPI-R64 sources can be found on
https://github.com/BPI-SINOVOIP/BPI-R64-openwrt

79e6820245 arm64: dts: renesas: Prepare AA1024XD12 panel .dtsi for overlay support 
The Mitsubishi AA1024XD12 panel can be used for R-Car Gen2 and Gen3
boards as an optional external panel. It is described in the
arm/boot/dts/r8a77xx-aa104xd12-panel.dtsi file as a direct child of the
DT root node. This allows including r8a77xx-aa104xd12-panel.dtsi in
board device trees, with other minor modifications, to enable the panel.

This is however not how external components should be modelled. Instead
of modifying the board device tree to enable the panel, it should be
compiled as a DT overlay, to be loaded by the boot loader.

Prepare the r8a77xx-aa104xd12-panel.dtsi file for this usage by
declaring a panel node only, without hardcoding its path. Overlay
sources can then include r8a77xx-aa104xd12-panel.dtsi where appropriate.

This change doesn't cause any regression as r8a77xx-aa104xd12-panel.dtsi
is currently unused. As overlay support for this panel has only been
tested with Gen3 hardware, and Gen2 support will require more
development, move the file to arch/arm64/boot/dts/renesas/.
