[Skiboot] [PATCH] slw: Move add_cpu_idle_state_properties() to add_opal_node()

[Shilpasri G Bhat]

05f52a8dd7c7e402896e049fd24f83d56b70aff4 core: Setup the OPAL DT node
before platform probe
add_cpu_idle_state_properties() was made local to slw.c in the above
commit which caused p7 systems to not populate the nap idle state in
DT. So moving add_cpu_idle_state_properties() to add_opal_node to fix
this bug.
