Ouch...

It is much more as the initial goal of the patch. This breaks MX6ULL.

The idea to add features instead of global SOC define is good, rather we
suffer from previous development, when we bound bunches of features
simply to the SOC type.

Agree - I am waiting for Breno's answer, but if we have a generally
agreement I tend to revert this until this change will be properly handled.
