perf,mm: Handle non-page-table-aligned hugetlbfs
A limited nunmber of architectures support hugetlbfs sizes that do not
align with the page-tables (ARM64, Power, Sparc64). Add support for
this to the generic perf_get_page_size() implementation, and also
allow an architecture to override this implementation.
This latter is only needed when it uses non-page-table aligned huge
pages in its kernel map.
