[PATCH] arm64: renesas: Separate 64bit only code

[Marek Vasut]

Conditionally compile code that is only compatible with 64bit ARMv8
on 64bit R-Car Gen3/4/5 SoCs. Protect such code with CONFIG_ARM64.
This split is implemented in preparation for build of Cortex-M33
version of R-Car Gen5 U-Boot for its RSIPM core.
