[PATCH 0/2] OPAL message log interface

[Joel Stanley]

These two patches add support for the message log, and expose a new OPAL call
called opal_invalid that allow me to cause OPAL to inject messages into the
log.

The naming is a bit mixed, as our device tree node is opal-memcons and I
retained the naming of the header structure 'struct memcons', but all other
references are to the OPAL message log.

They have been tested on a POWER7+ machine running some recent firmware.
