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.

rt2x00: write registers required for reducing power consumption
Write registers required for reducing power consumption like the vendor
driver does when ADJUST_POWER_CONSUMPTION_SUPPORT is set.
This helps devices to sync at better TX/RX rates and improves overall
performance.
