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.
