    nvme-pci: hybrid irq+polling

This commit introduces hybrid irq+polling for nvme-pci using the DIM framework
to adjust completion methods dynamically based on the workload.

[Severity: Medium]
Since DIMLIB is defined in lib/Kconfig with a dependency on NET, does
unconditionally selecting it here risk Kconfig unmet direct dependency
warnings and potential build failures on configurations where CONFIG_NET is
disabled?
