hv: pgtable: remove alloc_ept_page 

alloc_page/free_page should been called in pagetable module. In order to do this,
we add pgtable_create_root and pgtable_create_trusty_root to create PML4 page table
page for normal world and secure world.

After this done, no one uses alloc_ept_page. So remove it.
