x86/resctrl: Add __init attribute to rdt_get_mon_l3_config()
In an upcoming change, 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.
Add the __init attribute to rdt_get_mon_l3_config() that is only called by
get_rdt_mon_resources() that already has the __init attribute. Also make
rdt_cpu_has() available to by rdt_get_mon_l3_config() via the internal header
file.
