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.

Currently support for the ARM Cortex-A9 Snoop Control Unit is included
unconditionally, while only Renesas multicore Cortex-A9 SoCs have this
kind of SCU.
This decreases kernel image size by ca. 300 bytes on SoCs without such
an SCU.

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.

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.

Commit 59b89af1d5551c12 ("ARM: shmobile: sh7372: Remove Legacy C
SoC code") removed the last user of the rmobile_pm_domain.resume()
callback.
Commit 44d88c754e57a6d9 ("ARM: shmobile: Remove legacy SoC code
for R-Mobile A1") removed the last user of the rmobile_pm_domain.no_debug
flag and of the "pm-rmobile.h" header file (outside the actual driver).
Hence remove no longer used rmobile_pm_domain members, and absorb the
header file into the driver.

From: Geert Uytterhoeven <geert+renesas@glider.be>
The pm-rmobile driver is really a driver for the System Controller
(SYSC) found in R-Mobile SoCs. An equivalent driver for R-Car SoCs is
already located under drivers/soc/renesas/.
Hence move the pm-rmobile driver from arch/arm/mach-shmobile/ to
drivers/soc/renesas/, and rename it to rmobile-sysc.
Enable compile-testing on non-ARM and non-R-Mobile SoCs.
