commit 267b21d0be upstream.
According to DT spec, size of property 'alignment' is based on parent
node’s #size-cells property.
But __reserved_mem_alloc_size() wrongly uses @dt_root_addr_cells to get
the property obviously.
Fix by using @dt_root_size_cells instead of @dt_root_addr_cells.
Fixes: 3f0c820664 ("drivers: of: add initialization code for dynamic reserved memory")
