b1d134ba9d soc: renesas: Register SoC device early
The r8a7795 SYSC driver manages PM Domains, and thus is initialized from
an early_initcall().  However, this means the driver cannot check the
SoC revision, as the SoC device hasn't been registered yet.

Change renesas_soc_init() from a core_initcall() to an early_initcall()
to fix this (renesas-soc.o is listed before rcar-sysc.o in the Makefile).

8d6799a9ba 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
