net/qede: add infrastructure for debug data collection

Browse Source 
The patch adds QEDE PMD ops and APIs to calculate the size and collect
the debug dump for various firmware components. The patch adds new files
qede_debug.[ch] that has all the firmware debug data collection
infrastructure changes.
