staging: r8712u: Merging Realtek's latest (v2.6.6). Various fixes.

passive_mode added to private ioctls.
New private ioctls added for RSSI, link speed, mac address, scan type,
and DCE-D.
In r8711_wx_get_scan(), we now sleep only 100 times, instead of 1000.
In r8711_wx_set_essid(), added a check for Ad-Hoc state.
In r8711_wx_get_rate(), added a check for RTL8712_RF_2T2R RF type.
Added Set chplan.
In r871x_get_wireless_stats(), updated the mechanism for displaying
link quality.
Added SetDIG and SetRA commands.
r8712_joinbss_cmd() no longer checks for Ad-Hoc mode.
