kgdb: Make "kgdbcon" work properly with "kgdb_earlycon"
[ Upstream commit b18b099e04f450cdc77bec72acefcde7042bd1f3 ]
On my system the kernel processes the "kgdb_earlycon" parameter before
the "kgdbcon" parameter. When we setup "kgdb_earlycon" we'll end up
in kgdb_register_callbacks() and "kgdb_use_con" won't have been set
yet so we'll never get around to starting "kgdbcon". Let's remedy
this by detecting that the IO module was already registered when
setting "kgdb_use_con" and registering the console then.
As part of this, to avoid pre-declaring things, move the handling of
the "kgdbcon" further down in the file.
