Test case - disabling hpd polling

Hi Elizabeth,
  the hang/bug appears from 4.7.3, when hpd polling was introduced.

I disabled the hpd polling in 4.7.3 and 4.14.11: since now no more hangs.

On my platform (HP 250 G3 Notebook) it seems no problem are raised by disabling
it, even pm-suspend works fine (but I did not try with external monitor).

Is there any other test I could perform to better address the problem?

Thank you!
  Luca
