[PATCH] [media] ov9640: make const arrays res_x/y static const, reduces object code size

[Colin King]

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

Don't populate the arrays res_x and resy_y on the stack, instead make them
static const.  Makes the object code smaller by over 160 bytes:

Before:
   text    data     bss     dec     hex filename
  10509    2800      64   13373    343d ov9640.o

After:
   text    data     bss     dec     hex filename
  10184    2960      64   13208    3398 ov9640.o
