cfg80211/mac80211: Update set_tx_power to use mBm instead of dBm units
In preparation for a TX power setting interface in the nl80211, change the
.set_tx_power function to use mBm units instead of dBm for greater accuracy and
smaller power levels.
Also, already in advance move the tx_power_setting enumeration to nl80211.
This change affects the .tx_set_power function prototype. As a result, the
corresponding changes are needed to modules using it. These are mac80211,
iwmc3200wifi and rndis_wlan.
