Add support for dynamically adjusting the PCIe link rate of NVMe
devices based on I/O activity. The link is downgraded to a
configurable minimum rate during periods of low activity to save
power, and upgraded to the maximum supported rate as soon as the
workload exceeds a computed threshold, so that peak performance is
maintained under load.
