drm/amd/display: Initialize num_pkrs on VANGOGH.

Browse source

As far a I can tell uses a variant of DCN3xx which uses num_pkrs.

If we do not initialize the variable we will set the register field
to ilog2(0) = -1, though the mask will reduce that to 7. Pretty sure
7 is not the value we want here.
