Some SPI controllers can't write nor->page_size bytes in a single
step because their TX FIFO is too small.
Allow nor->write() to return a size that is smaller than the requested
write size to gracefully handle this case.

Some SPI controllers can't write nor->page_size bytes in a single
step because their TX FIFO is too small.
Allow nor->write() to return a size that is smaller than the requested
write size to gracefully handle this case.
