Michal Suchanek 59451e1233 mtd: spi-nor: change return value of read/write 
Change the return value of spi-nor device read and write methods to
allow returning amount of data transferred and errors as
read(2)/write(2) does.

Also, start handling positive returns in spi_nor_read(), since we want
to convert drivers to start returning the read-length both via *retlen
and the return code. (We don't need to do the same transition process
for spi_nor_write(), since ->write() didn't used to have a return code
at all.)
