[PATCH 1/2] spi: sun4i: Set bits_per_word_mask to only support 8 bits word length

[Axel Lin]

This controller only supports 8 bits word length.
Set bits_per_word_mask so spi core will reject transfers that attempt to use
an unsupported bits_per_word value.

[PATCH 2/2] spi: sun6i: Set bits_per_word_mask to only support 8 bits word length
