On rk808 buck1 and buck2 have programmable ramp delays.  Let's add a
function to allow a client of rk808 to set them.

1. Pass &pdev->dev rather than &client->dev to of_regulator_match, the *dev
   argument is used for devres to ensure devm_of_regulator_put_matches() will
   be called when unload the module.

2. of_get_child_by_name() returns a node pointer with refcount incremented.
   Thus add missing of_node_put(reg_np).

The original RK808 regulator driver didn't setup input supplies
properly.  Add them.

The min_sel is 0, max_sel is 15, so n_voltages should be 16.

The memory allocated in rk808_regulator_probe() needs to be freed when the
module is unloaded. Thus pass &pdev->dev rather than &client->dev to
devm_kzalloc.

The "dev" has been deleted from "struct rk808" in rk808 mfd driver
so rk808->dev should be replaced by &client->dev here.

The RK808 regulator driver was putting its config on the stack but not
initting it.  That means that you got a semi-random config.  Fix this.

The regulator module consists of 4 DCDCs, 8 LDOs and 2 switches.
The output voltages are configurable and are meant to supply power
to the main processor and other components
