cleanup domain builder declarations and related users
There are several unused function and structure declarations in the
hypervisor related to domain building. Remove them.
Use an enum for elf_dom_parms.pae instead of just hard coding the
values when setting the information and adjust the code to use those
instead of own macros (hypervisor and tools).
