Add an initial device tree for the Lenovo Tab P11. Currently it
enables:

- simplefb
- SD Card slot via SDHCI2
- gpio-keys & PON keys
- UFS
- RPM regulators
- USB2

This has been validated with a rev (62) device. You can check yours
next to the serial no. on the sticker in the lower portion of the
back side of your tablet.

To get a successful boot run:

cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/\
sm6115p-lenovo-j606f.dtb > .Image.gz-dtb

~/mkbootimg/mkbootimg.py \

--ramdisk some/initrd.img \
--pagesize 4096 \
--base 0x0 \
--kernel_offset 0x8000 \
--ramdisk_offset 0x1000000 \
--tags_offset 0x100 \
--cmdline 'SOME_CMDLINE' \
--dtb_offset 0x1f00000 \
--header_version 1 \
--os_version 11 \
--os_patch_level 2022-11 \
-o j606f.img

fastboot flash boot j606f.img
fastboot flash dtbo empty.img
fastboot flash recovery empty.img
fastboot reboot

Where empty.img is 2 zero-bytes.
