ARM: SoC: convert Tegra to SMP operations Convert Tegra to use struct smp_operations to provide its SMP and CPU hotplug operations. Tested on Harmony.

ARM: tegra: moving the clock gating procedure to tegra_cpu_kill The tegra_cpu_die was be executed by the CPU itslf. So the clock gating procedure won't be executed after the CPU hardware shutdown code. Moving the clock gating procedure to tegra_cpu_kill that will be run by another CPU after the CPU died.

ARM: tegra: add cpu_disable for hotplug The Tegra114 could hotplug the CPU0, but the common cpu_disable didn't support that. Adding a Tegra specific cpu_disable function for it.
