[PATCH 1/2] ath5k: constify stuff

From: Jiri Slaby
Date: Sat Mar 07 2009 - 04:28:15 EST

Make some structures const to place them in .rodata, since we won't
change them.

Most important parts of objdump -h:
- 0 .text 00011170
+ 0 .text 00011140
- 5 .rodata 0000828e
+ 5 .rodata 0000895e
- 13 .data 00000560
+ 13 .data 00000110
- 14 .devinit.data 00000260
