This series borrows the concept used on Tegra234 to scale EMC based on
CPU frequency and applies it to Tegra186 and Tegra194. Except that the
bpmp on those archs does not support bandwidth manager, so the scaling
iteself is handled similar to how Tegra124 currently works.

Three different subsystems and no single explanation of dependencies and
how this can be merged.
