510bb595de 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.

da2265b130 ARM: tegra: remove tegra specific cpu_disable() 
The tegra cpu_disable() function is the same as the generic version
in arch/arm/kernel/smp.c.  Therefore, it can be removed.

b811943160 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.
