UBUNTU: SAUCE: pci: prevent Intel NVMe SSDPEKKF from entering D3

BugLink: https://bugs.launchpad.net/bugs/1804588
It leads to the power consumption increases 2.8W during s2idle, while it
consumes much less idle if forbidding put Intel NVMe to D3 and before
entering S2Idle.

Windows doesn't put NVMe to D3 in Modern Standby, and uses its own APST
feature to do the power management. To leverage its APST feature during
s2idle, we can't disable nvme device while suspending, too.

So, here is what we do to the driver:
- Prevent nvme from entering D3,
- Prevent nvme from being disabled when suspending.
