ARM: at91: pm: prepare for multiplatform Split at91_pm_init() in three variants that are called by the respective SoCs .init_machine. This allows to remove the of_machine_is_compatible() calls and move at91_pm_init() out of arch_initcall() which is required for multiplatform.

ARM: appropriate __init annotation for const data Init data marked const should be annotated with __initconst for correctness and not __initdata. In some cases the array gathering references to that data has to be marked const as well. This fixes LTO builds that otherwise fail with section mismatch errors.
