   3 rt2x00: write registers required for reducing power consumption
   4
   5 Write registers required for reducing power consumption like the vendor
   6 driver does when ADJUST_POWER_CONSUMPTION_SUPPORT is set.
   7 This helps devices to sync at better TX/RX rates and improves overall
   8 performance.
