Martin Schwidefsky 386aa051fb s390/pci: remove per device debug attribute
The per-pci-device 'debug' attribute is ill defined. For each device
it prints the same information, the adapter interrupt bit vector for
irq numbers 0 & 1, the start of the global interrupt summary vector
and the global irq retries counter. Just remove the attribute and
the associated code.

Jan Glauber d0b0885316 s390/pci: performance statistics and debug infrastructure
Add support for reading the PCI function measurement block counters
provided by the hypervisor. Add two s390 debug features, one for
critical errors and one for tracing and provide wrappers to log data.
