wifi: cfg80211: use structs for TBTT information access

Make the data access a bit nicer overall by using structs. There is a
small change here to also accept a TBTT information length of eight
bytes as we do not require the 20 MHz PSD information.

This also fixes a bug reading the short SSID on big endian machines.
