Subject: [PATCH v4 05/13] arch/x86: Introduce a new config parameter RESCTRL

Introduces a new config parameter RESCTRL.

This will be used as a common config parameter for both Intel and AMD.
Each vendor will have their own config parameter to enable RDT feature.
One for Intel(INTEL_RDT) and one for AMD(AMD_QOS). It can be enabled or
disabled separately. The new parameter RESCTRL will be dependent on
INTEL_RDT or AMD_QOS.
