arm64: dts: broadcom: bcm4908: Fix cpu node for smp boot 

[ Upstream commit 8bd582ae9a ]

Add spin-table enable-method and cpu-release-addr properties for
cpu0 node. This is required by all ARMv8 SoC. Otherwise some
bootloader like u-boot can not update cpu-release-addr and linux
fails to start up secondary cpus.
