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. Convert the existing of_regulator_bulk_get_all() for this purpose. This function has no in-tree users, as the original patch [1] that used it was never landed. This patch changes the function ABI, but it is straightforward to convert users. The underlying code that supports the existing regulator_get*() functions has been reworked in previous patches to support this specific case. An internal OF-specific version of regulator_get(), of_regulator_get_optional(), is added for this. Also convert an existing usage of "dev && dev->of_node" to "dev_of_node(dev)".quoted
