target/ppc: code motion from translate_init.c.inc to gdbstub.c

All the code related to gdb has been moved from translate_init.c.inc
file to the gdbstub.c file, where it makes more sense.

Version 4 fixes the omission of internal.h in gdbstub, mentioned in
<87sg3d2gf5.fsf@linux.ibm.com>, and the extra blank line.
