ARM: 8485/1: cpuidle: remove cpu parameter from the cpuidle_ops suspend hook
The suspend() hook in the cpuidle_ops struct is always called on
the cpu entering idle, which means that the cpu parameter passed
to the suspend hook always corresponds to the local cpu, making
it somewhat redundant.
This patch removes the logical cpu parameter from the ARM
cpuidle_ops.suspend hook and updates all the existing kernel
implementations to reflect this change.
