Subject: [PATCH] net: phy: bcm7xxx: make array bcm7xxx_suspend_cfg static, reduces object code size

From: Colin Ian King <colin.king@...onical.com>

Don't populate the array bcm7xxx_suspend_cfg A on the stack, instead
make it static.  Makes the object code smaller by over 300 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
   6351	   8146	      0	  14497	   38a1	drivers/net/phy/bcm7xxx.o

After:
   text	   data	    bss	    dec	    hex	filename
   5986	   8210	      0	  14196	   3774	drivers/net/phy/bcm7xxx.o
