x86/cqm: Share PQR_ASSOC related data between CQM and CAT
PQR_ASSOC MSR contains the RMID used for preformance monitoring of cache occupancy and memory bandwidth. The upper 32bit of this MSR contain the CLOSID for cache allocation. So we need to share the information between the two facilities. Move the rdt data structure declaration into the shared header file and make the per cpu data structure containing the MSR values global.
