mac80211: rt2x00: remove patch causing low tx power
Remove 980-rt2x00-reduce-power-consumption-on-mt7620.patch which in
combination with the most recently added patch reportedly causes TX
power to be too weak.
"without patches rssi on receiver is ~ -23dBm with 980 about -35dBm,
with both patches drops below -40dBm. with 987 only ~-28dBm"
We may need to reconsider this once we have implemented TSSI.
