Subject: spi/fsl: unnecessary double init_completion removed

The double call to init_completion(&mpc8xxx_spi->done); is not needed
presumably this is a editing mistake only.

Subject: spi: spi-fsl-dspi: Remove spi-bitbang

DSPI module need cs change information in
a spi transfer. According to cs change, DSPI
will give last data the right flag. Bitbang
provide cs change behind the last data in
a transfer. So DSPI can not deal the last
data in every transfer properly, so remove
the bitbang in the driver.

Subject: spi: fsl-dspi: Remove possible memory leak of 'chip'

Move the check for spi->bits_per_word
before allocation, to avoid memory leak.
