From: Alistair Francis <alistair.francis@wdc.com>

Calling qdev_get_machine() in the soc_init function would result in
the following assert

    ../hw/core/qdev.c:858: qdev_get_machine: Assertion `dev' failed.

when trying to run

    ./qemu-system-aarch64 -S -display none -M virt -device fsl-imx7,help

as the machine wasn't created yet. We call qdev_get_machine() to obtain
the number of CPUs in the machine. So instead of initialising the CPUs in
the SoC init let's instead do it in the realise where the machine
will exist.
