rfkill: remove set_global_sw_state

rfkill_set_global_sw_state() (previously rfkill_set_default()) will no
longer be exported by the rewritten rfkill core.

Instead, platform drivers which can provide persistent soft-rfkill state
across power-down/reboot should indicate their initial state by calling
rfkill_set_sw_state() before registration.  Otherwise, they will be
initialized to a default value during registration by a set_block call.

We remove existing calls to rfkill_set_sw_state() which happen before
registration, since these had no effect in the old model.  If these
drivers do have persistent state, the calls can be put back (subject
to testing :-).  This affects hp-wmi and acer-wmi.

Drivers with persistent state will affect the global state only if
rfkill-input is enabled.  This is required, otherwise booting with
wireless soft-blocked and pressing the wireless-toggle key once would
have no apparent effect.  This special case will be removed in future
along with rfkill-input, in favour of a more flexible userspace daemon
(see Documentation/feature-removal-schedule.txt).

Now rfkill_global_states[n].def is only used to preserve global states
over EPO, it is renamed to ".sav".
