[U-Boot] [PATCH 1/3] dm9000: mark dump_regs() function as unused

[Andrew Ruder]

dump_regs() is a handy function to keep around for bringing up a new
dm9000-based board, but defining CONFIG_DM9000_DEBUG only adds the
function - nowhere currently uses it.  Rather than remove a potentially
useful function, let's just tell gcc to not emit a warning when it is
unused.
