spi: omap-uwire: Remove needless bits_per_word and speed_hz tests
SPI core validates both bits_per_word and speed_hz transfer parameters and
defaults to spi->bits_per_word and spi->max_speed_hz in case these per
transfer parameters are not set. This allows to remove two needless tests
from uwire_txrx() and uwire_setup_transfer().
