SKX has already been added by commit below in tip/x86/cpu:

commit d40671e30cb46e834651e0ce3d4590c915171414
Author: Dave Hansen <dave.hansen@linux.intel.com>

    x86, powercap, rapl: Add Skylake Server model number
    
    SKX uses similar RAPL interface as Broadwell server according to
    Jacob Pan.
