Subject: [PATCH 1/4] ARM: cpuidle: add const qualifier to cpuidle_ops member in structures

The core code does not modify smp_operations structures. To clarify it,
this patch adds 'const' qualifier to the 'ops' member of struct
of_cpuidle_method.

This change allows each arm cpuidle code to add 'const' qualifier to
its cpuidle_ops structure.
