The to-be-introduced I2C component prober needs to enable regulator supplies (and toggle GPIO pins) for the various components it intends to probe. To support this, a new "pure DT lookup" method for getting regulator supplies is needed, since the device normally requesting the supply won't get created until after the component is probed to be available. Add a new of_regulator_get_optional() function for this. This mirrors the existing regulator_get_optional() function, but is OF-specific. The underlying code that supports the existing regulator_get*() functions has been reworked in previous patches to support this specific case. Also convert an existing usage of "dev && dev->of_node" to "dev_of_node(dev)".
