[POWERPC] Add spinlock to request_phb_iospace()
request_phb_iospace() can be called from different CPUs at init
time (at least with my next patch) and thus needs a spinlock.
As for the next patch, this is a temporary workaround for 2.6.22
issues until my rewrite of IO mappings is ready (for 2.6.23)
