target/microblaze: Delay gdb_register_coprocessor() to realize

Currently the microblaze code calls gdb_register_coprocessor() in its
initfn.  This works, but we would like to delay setting up GDB
registers until realize.  All other target architectures only call
gdb_register_coprocessor() in realize, after the call to
cpu_exec_realizefn().

Move the microblaze gdb_register_coprocessor() use, bringing it
in line with other targets.
