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

Being not so familiar with the flow of SPI patches, I was told that you 
are taking care of spi patches recently?

Do you like to have a look to this patch?

Many thanks and best regards

Dirk
