spi: imx: style fixes
This change fixes some random style issues that I noticed while debugging the driver: Remove some double spaces, use tabs for indention instead of spaces if possible, fix comment style. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Mark Brown <broonie@kernel.org>
