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

[Axel Lin <axel.lin-8E1dMatC8ynQT0dZR+AlfA@public.gmane.org>]

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.
