Why require that the CODEC be clock master here - why not make this
configurable, reusing the properties from the generic and audio graph
cards?

This is partly because I'm not sure how to do it (yet), but mostly
because I don't have the hardware to test this (the 2 CODECs present on
my only i.MX6 board are both clock master)

Take a look at what the generic cards are doing, it's a library function 
asoc_simple_parse_daifmt().  It's not the end of the world if you can't
test it properly - if it turns out it's buggy somehow someone can always
fix the code later but an ABI is an ABI so we can't change it.
