libertas: Added support for host sleep feature
Existing "ethtool -s ethX wol X" command configures hostsleep
parameters, but those are activated only during suspend/resume,
there is no way to configure host sleep without actual suspend.
This patch adds debugfs command to enable/disable host sleep based on
already configured host sleep parameters using wol command.
