x86's /proc/cpuinfo has a per-core "model name" line; most 64-bit ARM
kernels don't. Raspberry Pi's kernel instead puts a single friendly
"Model" line at the end of /proc/cpuinfo (e.g. "Raspberry Pi 5 Model B
Rev 1.0"), and /proc/device-tree/model has the same string on any
device-tree-based board as a further fallback if even that's missing.
Try each in turn, matching real Pi 5 /proc/cpuinfo formatting.
