Implements a memory allocator for physically and virtually contiguous memory using "normal" sized (i.e. not huge) pages. Implementation based on emmericp/ixy#12.

This PoC works as follows:
This approach is not very magical to someone who understands paging, but still adds a fair amount of code (We could replace the existing dma_allocate function, as this implementation can of course also serve requests <2MiB).
In my initial tests it did not even fail once for allocations up to 16 pages (32MiB) on a system with 512 total pages.
