soc: renesas: Identify SoC and register with the SoC bus
Identify the SoC type and revision, and register this information with
the SoC bus, so it is available under /sys/devices/soc0/, and can be
checked where needed using soc_device_match().
Identification is done using the Product Register or Common Chip Code
Register, as declared in DT (PRR only for now), or using a hardcoded
fallback if missing.
Example:
Detected Renesas R-Car Gen2 r8a7791 ES1.0
...
# cat /sys/devices/soc0/{machine,family,soc_id,revision}
Koelsch
R-Car Gen2
r8a7791
ES1.0
