This patch adds a function that leads to conflating the "model"
property and the "compatible" property. This leads to opaque,
confusing and unclear code where ever it is used. I think it is
not good for the device tree framework to contribute to writing
Further, only two of the proposed users of this new function appear
to be proper usage. I do not think that the small amount of reduced
lines of code is a good trade off for the reduced code clarity and
for the potential for future mis-use of this function.
