Implement ia64_physmem_alloc() and use it consistently to get memory
before VM has been initialized. This includes:
1. Replacing pmap_steal_memory(),
2. Replace the handcrafted logic to allocate a naturally aligned VHPT,
3. Properly allocate the DPCPU for the BSP.
Ad 3: Appending the DPCPU to kernend worked as long as we wouldn't
cross into the next PBVM page. If we were to cross into the next
page, then there wouldn't be a PTE entry on the page table for it
and we would end up with a MCA following a page fault. As such,
this commit fixes MCAs occasionally seen.
