drm/tegra: hub: Increase buffer size to ensure all possible values can be stored
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/tegra/hub.c: In function ‘tegra_display_hub_probe’:
drivers/gpu/drm/tegra/hub.c:1106:47: warning: ‘%u’ directive output may be truncated writing between 1 and 10 bytes into a region of size 4 [-Wformat-truncation=]
drivers/gpu/drm/tegra/hub.c:1106:42: note: directive argument in the range [0, 4294967294]
drivers/gpu/drm/tegra/hub.c:1106:17: note: ‘snprintf’ output between 6 and 15 bytes into a destination of size 8
