Logan Gunthorpe d1402fc708 mm: introduce common STRUCT_PAGE_MAX_SHIFT define ...

This define is used by arm64 to calculate the size of the vmemmap
region.  It is defined as the log2 of the upper bound on the size of a
struct page.

We move it into mm_types.h so it can be defined properly instead of set
and checked with a build bug.  This also allows us to use the same
define for riscv.
