linux-yocto/4.4/4.8: uvesafb: provide option to specify timeout for task completion

Integrating the following patch:

[
   We try to make this change a generic extension, but it is
   actually for a corner case. When a VM (qemu) gets a very limited
   cpu bandwidth from host, which could be under a heavy load, the
   existing 5000 ms timeout could occur and trigger error messages
   in the task function's callers.

   This change adds a new timeout parameter so that we can tweak
   the value as a workaround or for troubleshooting purposes. In
   the infinite wait case, A warning message is printed at 5000ms
   interval.

   In real world, the current 5 sec is generous enough for a video
   request in my opinion, so this change could not be very useful.
