mac80211: Add support for BSS max idle period element
Parse the BSS max idle period element and set the BSS configuration
accordingly so the driver can use this information to configure the
max idle period and to use protected management frames for keep alive
when required.
The BSS max idle period element is defined in IEEE802.11-2016,
section 9.4.2.79
