[Impact]
We already have correct NVMe suspend-to-idle implementation, we can
remove workaround we carried in Ubuntu kernel.

[Fix]
Revert unnecessary no quirks we used as workaround.

[Test]
After the revert, both NVMe still use native power saving mechanism as
intended.

[Regression Potential]
Though unlikely, if there is any platform that uses legacy S3 and needs
to keep the NVMe device in D0 instead of D3, this might have impact on
that scenario.
