drm/i915/pci: Remove force_probe requirement for DG1

Dunno why we still have .require_force_probe=1 on DG1 after
all this time. I'm not aware of any real problems with DG1,
so get rid of the force_probe requirement.

Generally the difficulty with DG1 is that it requires a
4GiB BAR for the local memory, and that's not something
that works on every system.
