From: Arnab Basu <arnab.b...@freescale.com>
of_bus_default_count_cells can be used to get the #address-cells
and #size-cells defined by the current node's parent node. This
is required when using of_read_number to read from FDT nodes that
can be 32 or 64 bytes depending on values defined by the parent.
