    x86: fix compat guest handling of XENPF_enter_acpi_sleep
    
    Rather than blindly defining the native name to the compat one, when
    we want to pass the compat structure to a native function we ought to
    verify that their layouts match. With a respective xlat.lst entry
    there's then also no need anymore to do such aliasing.
    
    While cleaaning up that file I also noticed that the Cx and Px
    interface handling here has quite a few unnecessary #define-s - delete
    them.
