Some pre-production firmware has incorrect GSI values in the HCDP,
which tells us where the serial console port is, so we have to
do the auto-IRQ thing after all.
(This is in a function that will get removed if my recent early serial
console patches are accepted, but it would be convenient to have this
patch in the meantime.)
