[LOCAL] arm64: renesas_defconfig: Reduce NR_CPUS to 8

The maximum number of arm64 CPU cores (excluding the real-time core) in
Renesas ARM SoCs is 8.

The default value of NR_CPUS used to be 64, causing a negligible kernel
size increase of ca. 16 KiB, compared to the minimum needed value of 8.
As of commit 846a415bf4408ccd ("arm64: default NR_CPUS to
256"), the default value of NR_CPUS was increased to 256, increasing the
waste by another 78 KiB.

Reduce NR_CPUS to 8, reducing kernel size by ca. 94 KiB.
