I added this because I wanted to use it in the SPL. I can put it in the 
header file for my board but I think it would be better in an imx8m 
header file. If not the pinfunc header is there another imx8m header you 
could suggest ?

I can set the sion bit via the DT but I'm not using the DT n the SPL so 
it won't help much.
