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

Don't populate the array 'registers' on the stack but instead make it
static const. Makes the object code smaller by 10 bytes.

Before:
text data bss dec hex filename
20138 5196 128 25462 6376 staging/media/imx/imx7-mipi-csis.o

After:
text data bss dec hex filename
20032 5292 128 25452 636c staging/media/imx/imx7-mipi-csis.o

(gcc version 9.2.1, amd64)
