[PATCH v9 01/26] x86/resctrl: Add __init attribute for the functions called in resctrl_late_init

[Babu Moger <babu.moger@xxxxxxx>]

The function resctrl_late_init() has the __init attribute, but some
functions it calls do not. Add the __init attribute to all the functions
to maintain consistency throughout the call sequence.

Fixes: 6a445edce657 ("x86/intel_rdt/cqm: Add RDT monitoring initialization")
Fixes: def10853930a ("x86/intel_rdt: Add two new resources for L2 Code and Data Prioritization (CDP)")
Fixes: bd334c86b5d7 ("x86/resctrl: Add __init attribute to rdt_get_mon_l3_config()")
Suggested-by: Reinette Chatre <reinette.chatre@xxxxxxxxx>

v9: Moved the patch to the begining of the series.
    Fixed all the call sequences. Added additional Fixed tags.

v8: New patch.
