soc: renesas: Rework Kconfig and Makefile logic The goals are to: - Allow precise control over and automatic selection of which (sub)drivers are used for which SoC, - Allow adding support for new SoCs easily, - Allow compile-testing of all (sub)drivers, - Keep driver selection logic in the subsystem-specific Kconfig, independent from the architecture-specific Kconfig (i.e. no "select" from arch/arm64/Kconfig.platforms), to avoid dependencies. This is implemented by: - Introducing Kconfig symbols for all drivers and sub-drivers, - Introducing the Kconfig symbol SOC_RENESAS, which is enabled automatically when building for a Renesas ARM platform, and which enables all required drivers without interaction of the user, based on SoC-specific ARCH_* symbols, - Allowing the user to enable any Kconfig symbol manually if COMPILE_TEST is enabled, - Using the new Kconfig symbols instead of the ARCH_* symbols to control compilation in the Makefile, - Always entering drivers/soc/renesas/ during the build.

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.
