This patch is a continuation of work performed in [d88ca7e1a27e]
upstream and propagates the fix into non-upstreamed part of NXP
source tree.
Since FBINFO_MISC_USEREVENT is completely dropped, all previous
calls to fb_set_var() which were setting and dropping this flag
are now calling fbcon_update_vcs(), but only if fb_set_var()
return 0.
