regulator: dt-bindings: Convert Dialog DA9211 Regulators to DT schema

Convert the existing text-based DT bindings for Dialog Semiconductor DA9211
Voltage Regulators family to a DT schema. Examples are simplified, as these
are all equal.

-* Dialog Semiconductor DA9211/DA9212/DA9213/DA9223/DA9214/DA9224/DA9215/DA9225
- Voltage Regulator
-
-Required properties:
-- compatible: "dlg,da9211" or "dlg,da9212" or "dlg,da9213" or "dlg,da9223"
-  or "dlg,da9214" or "dlg,da9224" or "dlg,da9215" or "dlg,da9225"
-- reg: I2C slave address, usually 0x68.
-- interrupts: the interrupt outputs of the controller
-- regulators: A node that houses a sub-node for each regulator within the
-  device. Each sub-node is identified using the node's name, with valid
-  values listed below. The content of each sub-node is defined by the
-  standard binding for regulators; see regulator.txt.
-  BUCKA and BUCKB.
-
-Optional properties:
-- enable-gpios: platform gpio for control of BUCKA/BUCKB.
-- Any optional property defined in regulator.txt
-  - regulator-initial-mode and regulator-allowed-modes may be specified using
-    mode values from dt-bindings/regulator/dlg,da9211-regulator.h
