Subject: [PATCH] rt2x00: make const array glrt_table static

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

Don't populate array glrt_table on the stack but make it static.
Makes the object code a smaller by over 670 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
 131772	   4733	      0	 136505	  21539	rt2800lib.o

After:
   text	   data	    bss	    dec	    hex	filename
 131043	   4789	      0	 135832	  21298	rt2800lib.o
