Add initial SM6350 SoC and Sony Xperia 10 III (PDX213, Lena platform) device
trees. There is no sign of another Lena devices on the horizon, so a common
DTSI is not created for now. 10 III features a Full HD OLED display and 5G
support, among other nice things like USB3.

The bootloader is VERY unpleasant, to get a bootable setup you have to run:

mkbootimg --kernel arch/arm64/boot/Image.gz --ramdisk [some initrd] \
--dtb arch/arm64/boot/dts/qcom/sm6350-sony-xperia-lena-pdx213.dtb \
--cmdline "[some cmdline]" --base 0 --kernel_offset 0x8000 \
--ramdisk_offset 0x1000000 --dtb_offset 0x1f00000 --os_version 11 \
--os_patch_level "2021-08" --tags_offset 0x100 --pagesize 4096 \
--header_version 2 -o mainline.img

adb reboot bootloader

// You have to either pull vbmeta{"","_system"} from
// /dev/block/bootdevice/by-name/ or build one as a part of AOSP build process
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta_system \
vbmeta_system.img

fastboot flash boot mainline.img
fastboot erase dtbo // This will take approx 70s...
fastboot reboot
