platform/x86/amd/hsmp: Move structure and macros to header file 



This is in preparation to splitting ACPI and platform device drivers.
No logical change, move common structures, macros to hsmp.h,
add missed header files, remove unwanted header inclusions,
and re-order the header file in hsmp.c file.
