mac80211: adding 802.11n HT framework definitions
New structures:
- ieee80211_ht_info: describing STA's HT capabilities
- ieee80211_ht_bss_info: describing BSS's HT characteristics
Changed structures:
- ieee80211_hw_mode: now also holds PHY HT capabilities for each HW mode
- ieee80211_conf: ht_conf holds current self HT configuration
ht_bss_conf holds current BSS HT configuration
- flag IEEE80211_CONF_SUPPORT_HT_MODE added to indicate if HT use is
desired
- sta_info: now also holds Peer's HT capabilities
