ARM: rmobile: Add R-Car Generation 4 support
This adds R-Car Generation 4 (Gen4) support as Renesas ARM64 SoC.
In this version, reusing R-Car Gen3 lowlevel initialize routine [1]
and R-Car Gen3 memory map tables [2] .

[Marek: - Enable DTO support by default
- Sort the Kconfig lists
- Select RCAR_64 Kconfig option to pull in all the shared
Kconfig options with Gen3, and use where applicable to
deduplicate entries.
- Fix reference [2] typo in commit message
- Drop config options moved to Kconfig, rename rest to CFG_
accordingly to synchronize with upstream changes. Drop
removed CONFIG_VERY_BIG_RAM.
- Move board size limit to arch/Kconfig
- Move GICR_BASE to headers instead of common config]
