intel: Add Cannonlake PCI IDs for U-skus.

Platform enabling and its power-on are organized in different
skus (U x Y x S x H, etc). So instead of organizing it in
GT1 x GT2 x GT3 let's also use the platform sku.

This is a copy of merged i915's
commit e918d79a5d0a ("drm/i915/cnl: Add Cannonlake PCI IDs for U-skus.")

v2: Remove PCI IDs for SKU not mentioned in spec.
v3: Add kernel commit id for reference.
