Don't populate const array ucode_ofdm_rates on the stack, instead make it
static. Makes the object code smaller by 100 bytes:
Before:
text data bss dec hex filename
39482 564 0 40046 9c6e phy_cmn.o
After
text data bss dec hex filename
39326 620 0 39946 9c0a phy_cmn.o
(gcc 6.3.0, x86-64)

Please use 'brcmsmac:' as prefix instead of 'brcm80211:'.
