powercap / RAPL: mark rapl_ids array as __initconst
The RAPL ids are only tested in rapl_init() which is itself an __init function. For the MODULE_DEVICE_TABLE() file2alias doesn't care about the section, just about the symbol name. Therefore it's safe to mark the rapl_ids[] array as __initconst so its memory can be released after initialization is done.
