spi: altera: Use bits_per_word_mask
This driver does not work for bits_per_word greater than 16. Set bits_per_word_mask so spi core will reject transfers that attempt to use an unsupported bits_per_word value. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>
