A GPU is named from an embedded PCI ID table, the same on every machine

The router has no lspci, so its GeminiLake chip came up as 'Intel GPU
3185' beside the identical chip's 'Intel UHD Graphics 600' on hamtv.
A trimmed pci.ids — the graphics devices of Intel, AMD and NVIDIA, and the
virtual GPUs, 115 KB — rides in the binary and is consulted first; lspci
is the fallback for a card newer than the table. scripts/pci-ids-gpu.sh
regenerates it from the hub's copy.
