arm64: defconfig: Remove individual Renesas SoC entries

Remove explicit entries for individual Renesas SoCs from the defconfig
file.  Since all Renesas SoCs are enabled by default when ARCH_RENESAS
is selected, and ARCH_RENESAS is already enabled in the defconfig,
listing them separately is redundant.
