target/ppc: cpu_init: Deduplicate 745/755 SPR registration 

The 745 and 755 can share the HID registration, so move it all into
register_755_sprs, which applies for both CPUs.

Also rename that function to register_745_sprs, since the 745 is the
earliest of the two. This will help with separating 755-specific
registers in a subsequent patch.
