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.
