Remove driver-side release of BARs from the i915 driver.

I also applied it to drm-tip from today and submitted for xe and i915

pass by comment... the forcewake handling in the middle of BAR resizing
is insane but it's probably because it's already very late in the probe
sequence. Moving it to early probe like was done in xe would allow it to
be simplified too.
