spi: imx: remove unnecessary bit clearing in mx51_ecspi_config
This reverts patch 1476253cef (spi: imx: fix ecspi mode setup) The patch tried to fix something by clearing bits in the cfg variable, but cfg is initialized to zero on function entry. There are no bits to clear. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Mark Brown <broonie@kernel.org>
