Bug description:
[Impact]
MT7921 is disabled by default, and it affects the power consumption.
[Fix]
MTK pointed out we need this commit which is included in v5.16-rc1
bf3747ae2e25 mt76: mt7921: enable aspm by default
After ASPM is enabled, we found the card disappears after reboot sometimes,
so MTK provides another commit for it
https://patchwork.kernel.org/project/linux-mediatek/patch/70e27cbc652cbdb78277b9c691a3a5ba02653afb.1641540175.git.obj...@gmail.com/
[Test]
Verified on Dell machines with MT7921 wifi card.
[Where problems could occur]
Enable device ASPM is always risky, we've done our best to test these
patches, and no regression could be found.
