[SeaBIOS] [PATCH 3/3] Initialise debug output in handle_csm()

[David Woodhouse]

For a PCI serial port, we have to discover its location. Potentially on
every entry, since UEFI may shift it at some point during the boot process
from an early debug setup to a final location after real PCI enumeration.
