We want to use generic 8250 debug_ll code to get DEBUG_UNCOMPRESS working and to simplify the code. The old debug_ll code is no longer needed and the machine ID based detection is no longer used. Note that for most part there's no need to keep DEBUG_LL enabled. We now have CONFIG_SERIAL_EARLYCON working very early as long as the kernel cmdline has "earlycon" in it and the board specific dts file has chosen configured with with the port using stdout-path.
