Model should also use the form "fsl,mpc5121ads". I think lowercase is
also preferred.

This should be going away in short order. I hope to have some code
written soon which will use aliases for assigning the port number.

Hmmm, interesting. Perhaps it would be better to leave the interrupts
property out of this node and have a fsl,fifo-handle property pointing
to the fifo node.

fsl,mpc5121-psc-fifo. mpc512x isn't real, it's a made up wildcard.
It's better to be specific.
