[Skiboot] [PATCH 3/3] fsp/console: Always establish OPAL console API backend

[Benjamin Herrenschmidt]

Currently we only call set_opal_console() to establish the backend
used by the OPAL console API if we find at least one FSP serial
port in HDAT.

On systems where there is none (IPMI only), we fail to set it,
causing the console code to try to use the dummy console causing
an assertion failure during boot due to clashing on the device-tree
node names.

So always set it if an FSP is present
