Adds initial device tree for Xiaomi Redmi Note 8T, codename xiaomi-willow.
It uses the sm6125 SoC. Currently only boots into initrd shell over UART.
Requires appended DTB with qcom,board-id = <0x22 0x0> and
qcom,msm-id = <0x18a 0x10000> to actually boot.

If I read this correctly you need to supply board-id and msm-id in order
to be able to get this booting?

Even though we don't like them, I would prefer if you just add them in
the dts file, in this patch.

Apart from these few remarks your patches looks good, looking forward to
see more of this platform!

Yes, AFAICT the bootloader iterates over the appended DTBs and will
only boot if it finds one with those matching properties.
