Add rtl8180 wireless driver
This patch adds a mac80211 based wireless driver for the rtl8180 and rtl8185 PCI wireless cards. Also included are some rtl8187 changes required due to the relationship between that driver and this one. Michael Wu is primarily responsible for the initial driver and rtl8185 support. Andreas Merello provided the additional rtl8180 support. Thanks to Jukka Ruohonen for the donating a rtl8185 card! It was very helpful for the rtl8225z2 code. The Signed-off-by information below is collected from the individual patches submitted to wireless-2.6 before merging this driver upstream.
