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.

This series adds IPMI driver and arch glue for OPAL-firmware-based
powernv machines. The first change exposes the firmware's IPMI API, and
the second adds an actual driver.
IPMI folks: the IPMI driver could do with a little review, as it's not a
conventional BT/KCS/SMI SI, in that the low-level se
Recent OPAL firmare adds a couple of functions to send and receive IPMI
messages:

This change updates the token list and wrappers to suit, and adds the
platform devices for any IPMI interfaces.

The new driver is around for more than 2 years now, so the old one can
go. Getting rid of it helps the removal of the legacy .attach_adapter
callback of the I2C subsystem.

Update generic gup implementation with powerpc specific details.
On powerpc at pmd level we can have hugepte, normal pmd pointer
or a pointer to the hugepage directory.
