From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
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)
