    x86: add AMD RAPL MSR definitions to specialreg.h
    
    specialreg.h is the tree's MSR registry and already carries the Intel
    RAPL group. Add the AMD RAPL package/core energy and unit MSRs here so
    the hwpmc RAPL class can reference them without a private driver copy.
    Use the names Linux's msr-index.h gives these registers.
