[PATCH 2/2] mv643xx_eth: make eth_port_uc_addr_{get,set}() calls symmetric

["Dale Farnsworth" <dale@farnsworth.org>]

From: Gabriel Paubert <paubert@iram.es>

There is no good reason for the asymmetry in the parameters of
eth_port_uc_addr_get() and eth_port_uc_addr_set().  Make them
symmetric.  Remove some gratuitous block comments while we're here.

This is a clean-up patch that needn't be rushed upstream.  -Dale
