The iterators don't need to know what bt_kill_msk means.
All they need to know is if reduced Tx power is enabled
on an interface or not. So change the member of the
iterator to be a bool.

Many platforms have issues processing a wakeup signal
while they're still suspending, and will ignore it.
Since our device thinks it woke the platform, and the
platform ignored the signal, it will sleep without
WoWLAN being enabled as the device disables WoWLAN
when having woken the platform.
Resolve this by making the device wait for 10 seconds
after getting the suspend signal before waking up the
platform.

The driver distinguishes between power management and device's power
down enablement. Power management enablement depends both on driver's
module power parameters and mac80211 decision. The device's power down
depends only on driver's module power parameters. Change the driver to
always send Power Table command to enable or disable both power
management and device's power down.

Currently power management is supported only when only a single
virtual interface is present. The driver verifies number of created
interfaces and disables power management when multiple interfaces
present. However, this rule does not extend to a P2P device that is
handled differently in the firmware. If a P2P device is added power
management can remain enabled.
