I think the one other place that will need to be updated with this split
is the definition of INTEL_UC_FIRMWARE_DEFS in
drivers/gpu/drm/i915/gt/uc/intel_uc_fw.c --- we'll need a new JASPERLAKE
entry there now that's a duplicate of the ELKHARTLAKE one.

There are also a couple minor conflicts with other patches that have
just landed on drm-tip, but aside from that this looks reasonable to me.
