Revert "Merge remote-tracking branch 'arm-soc/for-next' into linaro-3.0"

This reverts commit c7e0c8535d73f8c5bf760926a2bd71c9840cf2ef, reversing
changes made to dfee09c8acf18e84fe197bb5d821d1e4e02d020f.

John Stultz reports that Panda doesn't boot anymore and 'git bisect'
indicated the merge commit itself as the culprit. The resulting kernel
log is:

Revert it so a later version of the arm-soc merge result can be used
instead.
