Allow virtual wiphys to be paused/unpaused to allow off-channel
operations. Pause will stop all TX queues for the wiphy and move the
STA into power save mode if in managed mode. Unpause wakes up the TX
queues and notifies the AP that the STA woke up if in managed mode.

The new struct ath_softc::sec_wiphy array is used to store information
about virtual wiphys and select which wiphy is used in calls to
mac80211. Each virtual wiphy will be assigned a different MAC address
based on the virtual wiphy index.

This is the initial step in allowing ath9k to register multiple
virtual radios (wiphys). The goal of virtual radios is to allow the
same radio to be shared for multiple virtual interfaces that may
operate on different channels. The mac80211 virtual interface support
is designed only for single channel operation and as such, it is not
suitable for this type of use. Anyway, it can be used on top of the
virtual radio concept, if desired (e.g., use two virtual radios to
handle two channels and then add multiple mac80211 virtual interfaces
on top of each virtual radio).
The new struct ath_wiphy is now registered as the driver data
structure for wiphy. This structure has a pointer to the shared (among
virtual wiphys of the same physical radio) struct ath_softc data. The
primary wiphy maintains the allocated memory for ath_softc. Secondary
(virtual) wiphys will only allocate the new ath_wiphy structure.
Registration of secondary wiphys is added in a separate patch.

Instead of using a hardcoded BSSID mask (mask for own addresses),
iterate through all active interfaces and determine the minimal mask
that covers all local addresses.
