arm: multi_v7_defconfig: Drop individual Renesas SoC entries

ARCH_RENESAS is already enabled in multi_v7_defconfig, which ensures that
all ARM32 Renesas SoCs are enabled by default. As a result, explicitly
listing individual Renesas SoC entries is redundant. Remove these entries
to simplify the configuration.
