ipmi/powernv: Fix minor locking bug

If ipmi_powernv_recv(...) is called without a current message it
prints a warning and returns. However it fails to release the message
lock causing the system to dead lock during any subsequent IPMI
operations.

This error path should never normally be taken unless there are bugs
elsewhere in the system.

drivers/char/ipmi: Add powernv IPMI driver

This change adds an initial IPMI driver for powerpc OPAL firmware. The
interface is exposed entirely through firmware: we have two functions to
send and receive IPMI messages, and an interrupt notification from the
firmware to signify that a message is available.
