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".
