ARM: rockchip: fix kernel hang during smp initialization

In the Linux kernel, the following vulnerability has been resolved:

ARM: rockchip: fix kernel hang during smp initialization

In order to bring up secondary CPUs main CPU write trampoline
code to SRAM. The trampoline code is written while secondary
CPUs are powered on (at least that true for RK3188 CPU).
Sometimes that leads to kernel hang. Probably because secondary
CPU execute trampoline code while kernel doesn't expect.

The patch moves SRAM initialization step to the point where all
secondary CPUs are powered down.

That fixes rarely hangs on RK3188:
[    0.091568] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000
[    0.091996] rockchip_smp_prepare_cpus: ncores 4
