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.

My WIP tree with a few out-of-tree patches to support
display, touchscreen, wifi, audio etc is here:
https://github.com/pundiramit/linux/commits/beryllium-mainline
v6: Renamed dts file to include vendor (xiaomi) name. Moved
reserved memory changes in the main node. Renamed model to
phone's pretty name. Removed the mmc drive strength comment
to avoid further confusion. Sorted the entries in alphabetical
order, but additional pinctrl entries are still defined at the
end to align with the upstream db845c dts.
v5: Bumped &tz_mem size from 0x2d00000 to 0x4900000 (to include
downstream &removed_region), all the way up to &qseecom_mem.
v4: Added more downstream reserved memory regions. It probably
need more work, but for now I see adsp/cdsp/wlan remoteprocs
powering up properly. Removed the regulator nodes not
required for the device, as suggested by Bjorn. Also added
couple of clocks to protected clocks, which is needed for
display to work.
v3: Added a reserved-memory region from downstream kernel to fix
a boot regression with recent dma-pool changes in v5.8-rc6.
v2: Updated machine compatible string for seemingly inevitable
future quirks.
