mac80211: rt2x00: write registers required for reducing power consumption

Browse Source 
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.
