Now that create_mapping uses fixmap slots to modify pte, pmd, and pud entries, we can access page tables anywhere in physical memory, regardless of the extent of the linear mapping. Given that, we no longer need to limit memblock allocations during page table creation, and can leave the limit as its default MEMBLOCK_ALLOC_ANYWHERE. We never add memory which will fall outside of the linear map range given phys_offset and MAX_MEMBLOCK_ADDR are configured appropriately, so any tables we create will fall in the linear map of the final tables.
