staging: vt6655: mac80211 conversion add main mac80211 functions
Replace existing vt6655_probe with one converted to mac80211
with the following operations
vnt_tx_80211
vnt_start
vnt_stop
vnt_add_interface
vnt_remove_interface
vnt_config
vnt_bss_info_changed
vnt_prepare_multicast
vnt_configure
vnt_set_key
vnt_get_tsf
vnt_set_tsf
vnt_reset_tsf
The following variables are also added.
basic_rates
mc_list_count
mac_hw
