target/ppc: Allow cpu compatiblity checks based on type, not instance
ppc_check_compat() is used in a number of places to check if a cpu object
supports a certain compatiblity mode, subject to various constraints.
It takes a PowerPCCPU *, however it really only depends on the cpu's class.
We have upcoming cases where it would be useful to make compatibility
checks before we fully instantiate the cpu objects.
ppc_type_check_compat() will now make an equivalent check, but based on a
CPU's QOM typename instead of an instantiated CPU object.
We make use of the new interface in several places in spapr, where we're
essentially making a global check, rather than one specific to a particular
cpu. This avoids some ugly uses of first_cpu to grab a "representative"
instance.
