s390/ctltreg: make initialization of control register save area explicit
Commit e1b9c2749af0 ("s390/smp: ensure global control register contents
are in sync") made the control register save area contained within the
lowcore at absolute address zero a resource which is used when
initializing CPUs. However this is anything but obvious from the code.
Add an ctlreg_init_save_area() function in order to make this explicit.
