Remove support for 8M pages in order to stop using hugepd.
Support for 8M pages will be added back later using the same
approach as for 512k pages, in extenso using contiguous page
entries in the regular page table.

At the moment it has to look into each helper to know if the

a lower size. I hope this can me handled by core-mm in the future.
There are probably several ways to implement stuff, so feedback is
