Subject: [PATCH v2 11/13] arm64: dts: qcom: sdm845-lg-common: Add
 bootloader-compatible board and MSM IDs

The original bootloader (fastboot) requires board and MSM IDs in order
to boot the kernel, so these have been added. When re-using the same
files to chainload U-Boot, these compatibles are also needed to ensure
proper booting.
