eth: fbnic: Add support to dump registers

Add support for the 'ethtool -d <dev>' command to retrieve and print
a register dump for fbnic. The dump defaults to version 1 and consists
of two parts: all the register sections that can be dumped linearly, and
an RPC RAM section that is structured in an interleaved fashion and
requires special handling. For each register section, the dump also
contains the start and end boundary information which can simplify parsing.
