spi/imx: set the inactive state of the clock according to the clock polarity
There are SPI devices which need a SPI clock with active low polarity and
high inactive state.
Add the setting of the inactive state ECSPIx_CONFIGREG:SCLK CTL
according to the clock polarity ECSPIx_CONFIGREG:SCLK POL:
DT without "spi-cpol" = 0 = clock active high polarity = inactive state low
DT with "spi-cpol" = 1 = clock active low polarity = inactive state high
