[PATCH] media: platform: sti: make a const array static, makes object smaller

[Colin King]

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

Don't populate the const array bws on the stack but instead it
static. Makes the object code smaller by 8 bytes:

Before:
   text    data     bss     dec     hex filename
  12504    4568       0   17072    42b0 media/platform/sti/hva/hva-h264.o

After:
   text    data     bss     dec     hex filename
  12272    4792       0   17064    42a8 media/platform/sti/hva/hva-h264.o

(gcc version 10.2.0)
