Unfortunately the reset framework is a DT only framework and there are
still non-DT platforms within mach-msm. Arnd suggested we push the
non-DT reset code down into the mach directory in the meantime. We're in
the process of adding the reset framework to DT enabled MSM platforms,
hopefully those get merged in 3.14.
