Subject: [PATCH 17/62] e1000e: Use static const

Using static const generally increases object text and decreases data size.
It also generally decreases overall object size.

   text	   data	    bss	    dec	    hex	filename
  30847	   1400	   7088	  39335	   99a7	drivers/net/e1000e/phy.o.new
  30861	   1400	   7088	  39349	   99b5	drivers/net/e1000e/phy.o.old
