[PATCH] soc: renesas: r8a78000: Drop duplicate "default ARCH_RENESAS"

[Duy Nguyen]

Hi,

> The Kconfig entry for ARCH_R8A78000 contains both "default y if 
> ARCH_RENESAS" and "default ARCH_RENESAS", which are sort-of duplicates.
> 
> Drop the latter, to restore consistency with the other ARM64 entries.
