device tree: track init times
With the introduction of a monotonic timer it is possible to track the individual times of each device's init() call. Add this ability behind a HAVE_MONOTONIC_TIMER option.
Example log messages: Root Device init 5 usecs CPU_CLUSTER: 0 init 66004 usecs PCI: 00:00.0 init 1020 usecs PCI: 00:02.0 init 456941 usecs PCI: 00:13.0 init 3 usecs PCI: 00:14.0 init 3 usecs PCI: 00:15.0 init 92 usecs PCI: 00:15.1 init 37 usecs PCI: 00:15.2 init 36 usecs PCI: 00:15.3 init 35 usecs PCI: 00:15.4 init 35 usecs PCI: 00:15.5 init 36 usecs PCI: 00:15.6 init 35 usecs PCI: 00:16.0 init 3666 usecs PCI: 00:17.0 init 63 usecs PCI: 00:1b.0 init 3 usecs PCI: 00:1c.0 init 89 usecs PCI: 00:1c.1 init 15 usecs PCI: 00:1c.2 init 15 usecs PCI: 00:1c.3 init 15 usecs PCI: 00:1c.4 init 15 usecs PCI: 00:1c.5 init 16 usecs PCI: 00:1d.0 init 4 usecs PCI: 00:1f.0 init 495 usecs PCI: 00:1f.2 init 29 usecs PCI: 00:1f.3 init 4 usecs PCI: 00:1f.6 init 4 usecs
