Thomas Weißschuh 3120b5f218 power: supply: core: mark attribute arrays as ro_after_init
The attribute arrays are only modified during the __init phase.
To protect them against intentional or accidental modification,
mark them as __ro_after_init.

To make sure no modifications are introduced, also mark the return
values of the accessors as const.
