Subject: [PATCH v2 09/11] arch/x86: Introduce new config parameter AMD_QOS

Introduces the new config parameter AMD_QOS. This parameter will be
used to enable cache and memory bandwidth allocation and monitoring
features on AMD processors. This will enable common config parameter
PLATFORM_QOS if selected.
