Geminilake also supports pooled EUs. Enable it.

It is unclear if the recommendation to disable it for 2x6 configurations
from commit e015dd69b2cf ("drm/i915/bxt: Add WaEnablePooledEuFor2x6")
should also apply to GLK, but the only userspace that uses this only
cares about the 3x6 configuration. See Beignet's commit 6901899ec90a
("Runtime: set the sub slice according to kernel pooled EU configure.").
