[Skiboot] [PATCH 2/2] ipmi-sel: Run power action immediately if host not up

[Joel Stanley]

Our normal sequence for a soft power action (IPMI 'power soft' or
'power cycle') involve receiving a SEL from the BMC, sending a message
to Linux's opal platform support which instructs the host OS to shut
down, and finally the host will request OPAL to cut power.

When the host is not yet up we will send the message to /dev/null, and
no action will be taken. This patches changes that behaviour to perform
the action immediately if we know how.
