This completes the show_sdb_tree functionality, with the
new informative fields.  The output for a verbose module is now
like this (long lines are unavoidable):

The code reported wrong addresses in the sdb dumps.  All sdb addresses
are relative, but the code was adding the base address twice.  Bug
exposed by a gateware image with two bridge levels.

Thanks David for reporting the problem.

If we don't allocate "arr" then the cleanup path will dereference it and
oops.

This module offers registration services for both carriers
(i.e. devices) and mezzanines (i.e. drivers). The matching for devices
and drivers is performed according to the IPMI standard for FRU
devices (Field Replaceable Units).

The code includes support for parsing an SDB tree if present in the FPGA,
and dumping it for diagnostics. SDB is not mandatory.

Files in this commit correspond to commit ab23167f in the master branch
of the project hosted on ohwr.org.
