Merge "pxa changes for v4.2 cycle" from Robert Jarzmik:

The main and only feature is the conversion of all pxa variants to clock
framework. This encompasses pxa25x, pxa27x and pxa3xx, for all boards.

This should be a disruptive cycle in the normally quiet pxa history, as
the change can break any platform, and the test were performed on only 4
boards (lubbock, zylonite, mioa701, cm-x300).
