[v4,04/11] platform/x86/amd/hsmp: Move structure and macros to header file

Commit Message

Suma Hegde Aug. 20, 2024, 10:29 a.m. UTC

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.
