Reinette Chatre 95953034fb x86/intel_rdt: Initialize bitmask of shareable resource if CDP enabled 
The platform informs via CPUID.(EAX=0x10, ECX=res#):EBX[31:0] (valid res#
are only 1 for L3 and 2 for L2) which unit of the allocation may be used by
other entities in the platform. This information is valid whether CDP (Code
and Data Prioritization) is enabled or not.

Ensure that the bitmask of shareable resource is initialized when CDP is
enabled.
