arm64: tegra: Device tree changes for v5.20-rc1

This adds and enables various hardware on Tegra234 (host1x, VIC, GPCDMA)
as well as the Control BackBone related device tree nodes on Tegra194
and Tegra234.

Native timers are enabled on Tegra186, Tegra194 and Tegra234, which
allow keeping track of SoC-wide timestamps as well as hardware watchdog
functionality.

The audio subsystem is enhanced with the Output Processing Engine (OPE)
on Tegra210 and later.

Finally there are a handful of minor cleanups and fixes.

arm64: tegra: Mark BPMP channels as no-memory-wc

The Tegra SYSRAM contains regions access to which is restricted to
certain hardware blocks on the system, and speculative accesses to
those will cause issues.

Patch 'misc: sram: Only map reserved areas in Tegra SYSRAM' attempted
to resolve this by only mapping the regions specified in the device
tree on the assumption that there are no such restricted areas within
the 64K-aligned area of memory that contains the memory we wish to map.

Turns out this assumption is wrong, as there are such areas above the
4K pages described in the device trees. As such, we need to use the
bigger hammer that is no-memory-wc, which causes the memory to be
mapped as Device memory to which speculative accesses are disallowed.

As such, the previous patch in the series,
'firmware: tegra: bpmp: do only aligned access to IPC memory area',
is required with this patch to make the BPMP driver only issue aligned
memory accesses as those are also required with Device memory.

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

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/.
