This updates the Calxeda cpuidle driver to use PSCI calls to powergate cores. This also enables cpuidle for the ECX-2000. This could possibly become a generic PSCI driver, but there are no other PSCI users in the kernel other than mach-virt. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Cc: "Rafael J.
