ARM: keystone: dts: add psci command definition
This commit adds definition for cpu_on, cpu_off and cpu_suspend commands. These definitions must match the corresponding PSCI definitions in boot monitor. Having those command and corresponding PSCI support in boot monitor allows run time CPU hot plugin.
