Commit d20d31748 (drm: Constify the pretty-print functions) causes the following
build warning:
drivers/gpu/drm/drm_fb_helper.c:127:3: warning: passing argument 1 of 'fb_get_options' discards 'const' qualifier from pointer target type [enabled by default]
Let's change the first argument of fb_get_options from 'char *' to 'const char *'
so that we can get rid of this warning.
