Subject: [PATCH 42/62] tg3: 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
 168118	    970	  41008	 210096	  334b0	drivers/net/tg3.o.old
 168286	    802	  41008	 210096	  334b0	drivers/net/tg3.o.new

Use DEFINE_PCI_DEVICE_TABLE not direct declarations.
