eth: dpaa2: constify dpaa2_ethtool_stats and dpaa2_ethtool_extras

Browse Source 
The 'dpaa2_ethtool_stats' and 'dpaa2_ethtool_extras' structures are
initialized in their declarations and never changed. So, constify them
to reduce the attack surface.

Before the patch (size dpaa2-ethtool.o):

   text	   data	    bss	    dec	    hex
  33433	   5992	      0	  39425	   9a01

After the patch (size dpaa2-ethtool.o):

   text	   data	    bss	    dec	    hex
  34937	   4488	      0	  39425	   9a01
