H A Dspapr.c5013c547 Sun Dec 06 21:23:20 CST 2015 David Gibson <david@gibson.dropbear.id.au> pseries: DEFINE_SPAPR_MACHINE

At the moment all the class_init functions and TypeInfo structures for the
various versioned pseries machine types are open-coded. As more versions
are created this is getting increasingly clumsy.

This patch borrows the approach used in PC, using a DEFINE_SPAPR_MACHINE()
macro to construct most of the boilerplate from simpler 'class_options' and
'instance_options' functions.

This patch makes a small semantic change - the versioned machine types are
now registered through machine_init() instead of type_init(). Since the
new way is how PC already did it, I'm assuming that's correct.
