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

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)
