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.

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.

The Tegra186 timer provides ten 29-bit timer counters and one 32-bit
timestamp counter. The Tegra234 timer provides sixteen 29-bit timer
counters and one 32-bit timestamp counter. Each NV timer selects its
timing reference signal from the 1 MHz reference generated by USEC,
TSC or either clk_m or OSC. Each TMR can be programmed to generate
one-shot, periodic, or watchdog interrupts.

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
