arm: introduce psci_smp_ops

Rename virt_smp_ops to psci_smp_ops and move them to arch/arm/kernel/psci_smp.c.
Remove mach-virt/platsmp.c, now unused.
Compile psci_smp if CONFIG_ARM_PSCI and CONFIG_SMP.

Add a cpu_die smp_op based on psci_ops.cpu_off.

Initialize PSCI before setting smp_ops in setup_arch.
Use psci_smp_ops if the platform doesn't provide its own smp_ops.

If PSCI is available on the platform, prefer psci_smp_ops over the
platform smp_ops.

Changes in v8:
- merge "prefer psci_smp_ops over mdesc->smp" into this patch.

Changes in v6:
- fixed return values for psci_smp_available and psci_init ifndef
CONFIG_ARM_PSCI.

Changes in v5:
- document psci_operations;
- psci_init returns NULL.
