arch/arm64/Kconfig.platforms has SoC-specific Kconfig symbols for
Renesas SoCs, while other vendors have only a single Kconfig symbol.

Increase consistency with other vendors by moving the SoC-specific
Kconfig symbols to drivers/soc/renesas/Kconfig.

Increase consistency with R-Car Gen1 and Gen2 SoCs on arm32 by
introducing a family-specific Kconfig symbol for R-Car Gen3
(ARCH_RCAR_GEN3), which enables family-specific hardware features.
While so far only a single family (R-Car Gen3 and derivatives) of
Renesas arm64 SoCs is supported by Linux, this will make it easier
to add support for other SoC families later.

The R-Car GPIO driver cannot be enabled when Renesas SoC's ARCH configs
(ARCH_RENESAS, ARCH_R8A7795, ARCH_R8A7796 and ARCH_R8A77965) are enabled
only.

As GPIOs are a critical resource for proper operation on Renesas
platforms, this patch selects GPIOLIB, just like is done for other SoC
vendors, and on Renesas arm32 SoCs.

The Kconfig symbol for Renesas 64-bit ARM SoCs has always been
ARCH_RENESAS, with ARCH_SHMOBILE being selected to reuse drivers shared
with Renesas 32-bit ARM and/or Renesas SuperH SH-Mobile SoCs.

Commit 9b5ba0df ("ARM: shmobile: Introduce ARCH_RENESAS")
started the conversion from ARCH_SHMOBILE to ARCH_RENESAS for Renesas
32-bit SoCs.  Now all drivers for Renesas ARM SoCs have gained proper
ARCH_RENESAS platform dependencies, there is no longer a need to select
ARCH_SHMOBILE.

With ARCH_SHMOBILE gone, move the ARCH_RENESAS section up, to restore
alphabetical sort order.

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.
