[PATCH 3/3] arm64: dts: qcom: Add initial support for Xiaomi Redmi Note 8T

[Eli Riggs]

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.
