Alexander Boettcher 5f0ba7d722 intel_fb: handle rapid config change gracefully
In case of very rapid config ROM change (<300ms), the linux driver may still
be in progress of applying the previous change (e.g. switching connector on/off).

During this progress all tasks may become not runnable (waiting for IRQ/timeouts
until hardware state settles), the newest config ROM change/signal gets
dispatched, which lead to continuing the previous change request, but not
to re-starting/re-applying the new config change. To avoid this situation,
explicitly track whether a previous config change was finished and track if an
interim config change request came in. If so, re-start the lx_user
task with the newest config change.

Fixes #4721
