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.
