[RFC PATCH 08/11] target/ppc: wrapped some TCG only logic with ifdefs

["Bruno Larsen (billionai)" <bruno.larsen@eldorado.org.br>]

Wrapped some function calls in cpu_init.c and gdbstub.c that were TCG only
with ifdef CONFIG_TCG, to make it easier to build without it.

This seemed to be the minimum amount of changes to make the project
compile, but we wanted some feedback about wether we excluded something
important or if we should reorder some code to minimize ifdef count
