When converting from int to string, we must allow for up to 10-chars
(2147483647).
Fixes the following W=1 kernel build warning(s):
drivers/gpu/drm/imx/ipuv3/imx-ldb.c: In function ‘imx_ldb_probe’:
drivers/gpu/drm/imx/ipuv3/imx-ldb.c:659:39: warning: ‘_sel’ directive writing
4 bytes into a region of size between 3 and 13 [-Wformat-overflow=]
drivers/gpu/drm/imx/ipuv3/imx-ldb.c:659:17: note: ‘sprintf’ output between 8
and 18 bytes into a destination of size 16
