[PATCH 08/16] arm: really allocate boot frametable pages with 32M alignment

[Ian Campbell <ian.campbell@citrix.com>]

This argument to alloc_boot_pages is "pfn_align" and not an order.
We've been lucky until now that the area given to the boot allocator
happened to be properly aligned and this allocation was early enough
to benefit.
