    linuxkpi: Use `__builtin_popcountg()` instead of `bitcount*()`
    
    The DRM drivers generic code started to use `HWEIGHT64()` in the
    definition of an array field in a structure. Therefore, the array size
    needs to be known at compile time. This was not the case with the
    `HWEIGHT*()` macros based on `bitcount*()`. The use of
    `__builtin_popcountg()` solves that problem.
