While the override #define-s in x86_64/platform_hypercall.c are good for
the consuming side of the compat variants of set_{cx,px}_pminfo(), the
producers lack the respective declarations. Include pmstat.h early,
before the overrides are put in place, while adding explicit
declarations of the compat functions (alongside structure forward
declarations).

Thanks for the patch.  I'll give it a spin along with the other 8.4 fixes.
