Provide coverage to PCIe registers in ethtool register dump

The CSR dump support leverages the FBNIC_BOUNDS macro, which pads the end
condition for each section by adding an offset of 1. However, the RPC RAM
section, which is dumped differently from other sections, does not rely
on this macro and instead directly uses end boundary address. Hence,
subtracting 1 from the end address results in skipping a register.

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.
