intel/pci_ids: Drop non-upstream dg2 pci-ids

intel/pci_ids: Drop non-upstream dg2 pci-ids

These pci-ids should be included in
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/14523, since
these pci-ids will only be supported by kernels that support the
forked Linux uapi. (Note that !14523 will never be merged into
upstream Mesa.)
