x86/intel_rdt: Add command line options for resource director technology

Browse Source 
Command line options allow us to ignore features that we don't want.
Also we can re-enable options that have been disabled on a platform
(so long as the underlying h/w actually supports the option).

[ tglx: Marked the option array __initdata and the helper function __init ]
