Michal Meloun 878ca242eb Add regulator framework, a next part of new 'extended resources' family of
support frameworks(i.e. clk/reset/phy/tsensors/fuses...).

The framework is still far from perfect and probably doesn't have stable
interface yet, but we want to start testing it on more real boards and
different architectures.
