96e023e753 powerpc/powernv: Reorder OPAL subsystem initialisation
Most of the OPAL subsystems are always compiled in for PowerNV and
many of them need to be initialised before or after other OPAL
subsystems. Rather than trying to control this ordering through
machine initcalls it is clearer and easier to control initialisation
order with explicit calls in opal_init.

b14726c51c powerpc/powernv: Switch powernv drivers to use machine_xxx_initcall()
A lot of the code in platforms/powernv is using non-machine initcalls.
That means if a kernel built with powernv support runs on another
platform, for example pseries, the initcalls will still run.

That is usually OK, because the initcalls will check for something in
the device tree or elsewhere before doing anything, so on other
platforms they will usually just return.

But it's fishy for powernv code to be running on other platforms, so
switch them all to be machine initcalls. If we want any of them to run
on other platforms in future they should move to sysdev.

struct OpalMemoryErrorData is passed to us from firmware, so we
have to byteswap it.

75eb3d9b60 powerpc/powernv: Get FSP memory errors and plumb into memory poison infrastructure.
Get the memory errors reported by opal and plumb it into memory poison
infrastructure. This patch uses new messaging channel infrastructure to
pull the fsp memory errors to linux.
