of/flattree: eliminate cell_t typedef
A cell is firmly established as a u32. No need to do an ugly typedef to redefine it to cell_t. Eliminate the unnecessary typedef so that it doesn't have to be added to the of_fdt header file Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Tested-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
