drm/i915: allow to load DMC firmware on next gen

Browse source 
Before commit d8a5b7d79f ("drm/i915/csr: keep max firmware size together
with firmare name and version") it was possible to load the firmware for
testing purposes via parameter. Let's use the size of the last known
platform to recover that behavior.
