Subject: [PATCH 02/18] ARM: add const qualifier to smp_operations member in structures

The core framework does not modify smp_operations structures.
To clarify it, this commit adds 'const' qualifier to the 'ops'
member of struct of_cpu_method and the 'smp' member of struct
machine_desc.

This change allows each SoC code to add 'const' qualifier to its
smp_operation structure.
