MT7921[14c3:7961] ASPM is disabled and it affects power consumption

[AceLan Kao]

[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<email address hidden>/

[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.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-oem-5.14/5.14.0-1028.31 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
