DaVinci SoC updates for v4.21
-----------------------------

This set of patches moves DaVinci one step closer to
not relying on at24 platform data by relying on nvmem
cell lookups instead.

Once other dependencies are merged, for v4.22, plan is
to merge another series of patches removing at24
platform data.

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.

Unlike all other family-specific Kconfig symbols for Renesas ARM SoCs,
ARCH_RZN1 is user-visible.  As this symbol is already selected by the
SoC-specific ARCH_R9A06G032 symbol, there is no need for that.

Hide ARCH_RZN1 from the user, and move it up, where all other
family-specific Kconfig symbols live.  Drop the select of CPU_V7, as
this is already implied by the dependency of ARCH_RENESAS on
ARCH_MULTI_V7.
