target/ppc: cpu_init: Move check_pow and QOM macros to a header
These will need to be accessed from other files once we move the CPUs
code to separate files.
The check_pow_hid0 and check_pow_hid0_74xx are too specific to be
moved to a header so I'll deal with them later when splitting this
code between the multiple CPU families.
