[Skiboot] [PATCH 1/4] FSP/CONSOLE: Do not associate unavailable console

[Vasant Hegde]

Presently OPAL sends Associate/unassociate MBOX command for all
FSP serial console (like below OPAL message). We have to check
console is available or not before sending this message.

OPAL log:
-------
[ 5013.227994012,7] FSP: Reassociating HVSI console 1
[ 5013.227997540,7] FSP: Reassociating HVSI console 2
