-On Armada 38x SoCs, under heavy I/O load, the system hangs when CPU
-Idle is enabled. Waiting for a solution to this issue, this patch
-disables the CPU Idle support for this SoC.
-
-As CPU Hot plug support also uses some of the CPU Idle functions it is
-also affected by the same issue. This patch disables it also for the
-Armada 38x SoCs.

-In this version I removed the unneeded initialization of the ret
-variable, I also fixed the warning message, and finally I added the
-Tested-by from Thomas.
