ixgbe: Refactor common code between 82598 & 82599 to accommodate new hardware

Some of the following MAC functions are moved from 82598 & 82599 specific
hardware files to common.[ch] to accommodate new silicon changes. Also
fixed some white space issues
 * get_san_mac_addr, check_link, set_vmdq, clear_vmdq, clear_vfta,
 * set_vfta, fc_enable, init_uta_tables
