[PATCH] mwifiex: make const arrays static to shink object code size

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Don't populate const arrays on the stack, instead make them static
Makes the object code smaller by nearly 300 bytes:

Before:
   text    data     bss     dec     hex filename
  69260   16149     576   85985   14fe1 cfg80211.o

After:
   text    data     bss     dec     hex filename
  68385   16725     576   85686   14eb6 cfg80211.o
