Subject: [PATCH] [media] dib0090: make const array dib0090_tuning_table_cband_7090e_aci static

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

Don't populate array dib0090_tuning_table_cband_7090e_aci on the stack but
instead make it static. Makes the object code smaller by over 180 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  40052	   7320	    192	  47564	   b9cc dib0090.o

After:
   text	   data	    bss	    dec	    hex	filename
  39780	   7408	    192	  47380	   b914	dib0090.o
