Device trees for newer SoCs avoid replicating the entire device
hierarchy in the board-specific device tree part. Instead,
they set additional properties only by referencing labels,
sorted alphabetically.
Now that we have labels for all relevant nodes, convert the MSM8916
board device trees to use the same style and remove the "soc" node
entirely.
Note: There is a large block of coresight nodes in apq8016-sbc.dtsi,
which are enabled by setting status = "okay". I kept them grouped
together (not alphabetically sorted with everything else),
since that would be just unnecessarily verbose and hard to see.
This commit only moves all existing properties to nodes that reference
the respective label. The resulting binary DTBs are exactly the same.

Add a few more labels to device nodes declared in msm8916.dtsi
so that we can set all needed properties using labels in the
board-specific device tree part.
Also rename the "otg" label to "usb" to allow grouping it with
the USB PHY (usb_hs_phy) node when ordering referenced labels
alphabetically.

The leds node does not use any memory regions of the SoC and should
therefore be declared outside the "soc" node.

The "sound" node in apq8016-sbc.dtsi references memory regions
provided by the SoC and should be therefore declared in msm8916.dtsi.
Additionally, the machine driver used for the "qcom,apq8016-sbc-sndcard"
compatible also works on other MSM8916 devices (provided that audio
routing is set up properly). It is not really specific to apq8016-sbc.
Simplify setting up sound on other boards by moving the common part
to msm8916.dtsi. This also allows referencing the node by the label,
so that we can eventually drop the "soc" node entirely from the
board-specific device tree part and use labels exclusively.

Add initial dts support for Xiaomi Poco F1 (Beryllium).
This initial support is based on upstream Dragonboard 845c
(sdm845) device. With this dts, Beryllium boots AOSP up to
ADB shell over USB-C.
Supported functionality includes UFS, USB-C (peripheral),
microSD card and Vol+/Vol-/power keys. Bluetooth should work
too but couldn't be verified from adb command line, it is
verified when enabled from UI with few WIP display patches.
Just like initial db845c support, initializing the SMMU is
clearing the mapping used for the splash screen framebuffer,
which causes the device to hang during boot and recovery
needs a hard power reset. This can be worked around using:
fastboot oem select-display-panel none
To switch ON the display back run:
fastboot oem select-display-panel
But this only works on Beryllium devices running bootloader
version BOOT.XF.2.0-00369-SDM845LZB-1 that shipped with
Android-9 based release. Newer bootloader version do not
support switching OFF the display panel at all.

The 'sustainable_power' attribute provides an estimate of the sustained
power that can be dissipated at the desired control temperature. One
could argue that this value is not necessarily the same for all devices
with the same SoC, which may have different form factors or thermal
designs. However there are reasons to specify a (default) value at SoC
level for SC7180: most importantly, if no value is specified at all the
power_allocator thermal governor (aka 'IPA') estimates a value, using the
minimum power of all cooling devices of the zone, which can result in
overly aggressive thermal throttling. For most devices an approximate
conservative value should be more useful than the minimum guesstimate
of power_allocator. Devices that need a different value can overwrite
it in their <device>.dts. Also the thermal zones for SC7180 have a high
level of granularity (essentially one for each function block), which
makes it more likely that the default value just works for many devices.
The values correspond to 1901 MHz for the big cores, and 1804 MHz for
the small cores. The values were determined by limiting the CPU
frequencies to different max values and launching a bunch of processes
that cause high CPU load ('while true; do true; done &' is simple and
does a good job). A frequency is deemed sustainable if the CPU
temperatures don't rise (consistently) above the second trip point
('control temperature', 95 degC in this case). Once the highest
sustainable frequency is found, the sustainable power can be calculated
by multiplying the energy consumption per core at this frequency (which
can be found in /sys/kernel/debug/energy_model/) with the number of
cores that are specified as cooling devices.
The sustainable frequencies were determined at room temperature
on a device without heat sink or other passive cooling elements.

The power keeps going on here so I haven't have a chance to give this the
testing I usually would, but I don't have a Kendryte anyway so I doubt I'd pick
up anything subtle even if I was to test. The patch seems pretty safe and it's
still early, so I don't see any reason to let it sit around.
It's fairly late so if it misses the merge window that's not a big deal. I'll
definately have stuff for next week, so I'll just start from whenever this
lands.
