[PATCH] spi: sh-msiof: Kill sh_msiof_spi_bits and sh_msiof_spi_hz functions

[Axel Lin]

In the implementation of __spi_validate(), spi core will set transfer
bits_per_word and max speed as spi device default if it is not set for
this transfer. So we can remove the same implementation in this driver.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
