G2 Panels: Automatically detect panel command line (AOSP)

Revert the CAF mdss driver before autogenerated dtsi files, dtsi v2

Since our 4.2 bootloader cannot read the new format and we must force LGD or JDI, revert the changes so we can have the bootloader automatically detect the panel maker and automatically apply the command line again

Also create a new header oldbootloader.h in order to use get_panel_maker_id without breaking anything else

Change all panel dtsi and msm8974-mdss to use the old panel commands

This currently does not boot on stock roms due to missing dependencies that we must add back
