Add a generic helper to fill and enable simplefb nodes.
The first user of this will be the sunxi display code.
lcd_dt_simplefb_configure_node is also a good candidate to be converted to use this, but that requires someone to run some tests first, as lcd_dt_simplefb_configure_node does not honor #address-cells and #size-cells, but simply assumes 1 and 1 for both.

Please see lcd_dt_simplefb_configure_node() which seems similar.
