[Fix] MTK pointed out we need this commit which is included in v5.16-rc1 bf3747ae2e25 mt76: mt7921: enable aspm by default [Test] Verified on Dell machines with MT7921 wifi card. [Where problems could occur] Enable device ASPM is always risky, but MT7921 is a rather new device, and MTK submitted the patch at June, so it should be safe to enable ASPM on this new device and there is no follow up fixes commit after ASPM is enabled.
