Sync the SoC IDs in qcom,ids.h with relevant entries from Qualcomm's LK 
bootloader that is used for almost all older Qualcomm SoCs. This is 
meant to reduce the effort for future SoC bring-up (to avoid having to 
send a separate patch series for each new SoC) and will also benefit 
other projects using the same dt-bindings, e.g. bootloaders where 
adding support for all these SoCs is a bit easier than on Linux.

Independent of the question about qcom,msm-id and qcom,board-id, I would
like these constants for the socinfo driver (as shown in patch 4).

Would you prefer that we keep a separate list in Linux?

Thanks,
