I might as well fix it since I have to make changes anyway. Don't 
remember how I came up with 6.

I omitted this on purpose. For my use case, I am using the SPI as 
write-only, so not using the SOMI pin, which is actually muxed as a GPIO 
for something else. So having a pinctl like spi1 is of no use to me. I 
figured if someone needs it, they can add it, otherwise it just is 
wasted space to me.

Ack.
