[U-Boot] [Patch v2 4/5] ARMv8/ls2085a: Enable secondary cores

Spin table is at the very beginning of boot code. Each core has an individual
release address within the spin table, the ft_cpu_setup fn updates the
"cpu-release-addr" property of each cpu node with the corresponding release
address.

Also fix CPU_RELEASE_ADDR to point to secondary_boot_func.
