[PATCH v9 06/13] x86/resctrl: Add __init attribute to rdt_get_mon_l3_config()

[Babu Moger]

The function rdt_get_mon_l3_config() needs to call rdt_cpu_has() to
query the monitor related features. It cannot be called right now
because rdt_cpu_has() has the __init attribute but rdt_get_mon_l3_config()
doesn't. So, add the __init attribute to rdt_get_mon_l3_config() to
resolve it.

Also, make the function rdt_cpu_has() available outside core.c file.
