Laurent Vivier deeb956c40 trace-events,pci: unify trace events format
Unify format used by trace_pci_update_mappings_del(),
trace_pci_update_mappings_add(), trace_pci_cfg_write() and
trace_pci_cfg_read() to print the device name and bus number,
slot number and function number.

For instance:

  pci_cfg_read virtio-net-pci 00:0 @0x20 -> 0xffffc00c
  pci_cfg_write virtio-net-pci 00:0 @0x20 <- 0xfea0000c
  pci_update_mappings_del d=0x555810b92330 01:00.0 4,0xffffc000+0x4000
  pci_update_mappings_add d=0x555810b92330 01:00.0 4,0xfea00000+0x4000

becomes

  pci_cfg_read virtio-net-pci 01:00.0 @0x20 -> 0xffffc00c
  pci_cfg_write virtio-net-pci 01:00.0 @0x20 <- 0xfea0000c
  pci_update_mappings_del virtio-net-pci 01:00.0 4,0xffffc000+0x4000
  pci_update_mappings_add virtio-net-pci 01:00.0 4,0xfea00000+0x4000
