        src/sys/dev/pci: ppb.c ppbvar.h

Log Message:
 Enable PCIe's interrupt as much as possilbe in ppb(4) to detect and count
status change event. HotPlug function itself have not implemented yet.

 - Interrupt and each event are counted by evcnt(9). Example:

   ppb0 Interrupt                                                0    0 intr
   ppb0 Attention Button Pressed                                 0    0 misc
   ppb0 Power Fault Detected                                     0    0 misc
   ppb0 MRL Sensor Changed                                       0    0 misc
   ppb0 Presence Detect Changed                                  0    0 misc
   ppb0 Command Completed                                        0    0 misc
   ppb0 Data Link Layer State Changed                            0    0 misc

 - Print message if ppb_printevent is not zero. The default vaule is 0.
   The output messages:

   Attention Button Pressed
   Power Fault Detected
   MRL Sensor Changed
   Presence Detect Changed
   Command Completed
   Data Link Layer State Changed

 - Remove workaround code to disable interrupt (ppb.c rev. 1.35).

 Tested with Dell Latitude 2120 without if_bge.c rev. 1.304's workaround.
dmesg when bge's device timeout occured:

   ppb3: Presence Detect Changed
   ppb3: Data Link Layer State Changed
   ppb3: Presence Detect Changed

vmstat -e |grep ppb

   ppb3 Interrupt                                             2    0 intr
   ppb3 Presence Detect Changed                               2    0 misc
   ppb3 Data Link Layer State Changed                         1    0 misc
