Subject: [PATCH] mt76: mt7921: Disable powersave features by default
This brings WiFi latency down considerably and makes latency consistent by
disabling runtime PM and typical powersave features by default. The actual
power consumption difference is inconsequential on desktops and laptops,
while the performance difference is monumental. Latencies of 20+ ms are no
longer observed after this change, and the connection is much more stable.
