debugpci: Add tool for diagnosing common PCIe errors 
This tool captures and dumps common PCIe link errors for
PCIe devices on the bus which use the Synopsys DesignWare
controllers.
The DW controllers provide software mechanisms to detect
PCIe link errors. Capturing and dumping this debug information
in a systematic method helps reduce effort in debugging common
PCIe issues. It also provides debug suggestions for the
different errors wherever possible
