[PATCH] gpu: ipu-v3: make const arrays int_reg static, shrinks object size

[Colin King]

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

Don't populate the const read-only arrays int_reg on the stack but instead
make them static. Makes the object code smaller by over 80 bytes:

Before:
   text    data     bss     dec     hex filename
  28024    8936     192   37152    9120 drivers/gpu/ipu-v3/ipu-common.o

After:
   text    data     bss     dec     hex filename
  27794    9080     192   37066    90ca drivers/gpu/ipu-v3/ipu-common.o

(gcc version 7.2.0 x86_64)
