Because I do not want to patch kernel every time I need a new lookup.
Furthermore, looking at function imx53_qsb_init in imx53-dt.c, you
will find that lookup for sgtl5000 is really board specific and should
go to device tree.

It turns a property into 185 nodes, which will just bloat the device
tree.  This issue has been discussed for a plenty of times.
