When building with gcc 9.2.0, the following build warning was seen:
drivers/video/sunxi/sunxi_display.c: In function 'video_hw_init':
drivers/video/sunxi/sunxi_display.c:1217:2:
error: '%s' directive argument is null [-Werror=format-overflow=]
Change sunxi_get_mon_desc() to not return NULL for the default case,
to fix the compiler warning.
