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

commit d40671e30cb46e834651e0ce3d4590c915171414
Author: Dave Hansen <dave.hansen@...ux.intel.com>
Date:   Thu Jun 2 17:19:55 2016 -0700

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