scripts/extract_dts_includes: extract_reg_prop handle cells being 0

Browse source 
Its possible that #size-cells is 0 (ie i2c bus).  So we should handle
either #address-cells or #size-cells being 0 in extract_reg_prop.  This
means that the reg property in reduced map will end up being an integer,
so we need to convert it to a list with one element.  We also need to
not output any address-cell or size-cell related info if the respective
cell is 0.
