dt-bindings: mfd: dlg,da9063: Convert da9062 to json-schema

Convert the da9062 PMIC device tree binding documentation to json-schema.

Document the missing gpio child node for da9062.

While at it, update description with link to product information and
example.

The missing child node with of_compatible defined in MFD_CELL_OF is
causing the below warning message:
da9062-gpio: Failed to locate of_node [id: -1]

So, make all child nodes with of_compatible defined in struct mfd_cell
as required property for da906{1,2} devices.

The "gpio-controller" and "#gpio-cells" properties are defined in the
parent instead of gpio child node as there are existing driver users
based on these parent properties.

-Required properties:
-
-- compatible : Should be
-    "dlg,da9062" for DA9062
-    "dlg,da9061" for DA9061
-- reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
-  modified to match the chip's OTP settings).
-
-Optional properties:
-
-- gpio-controller : Marks the device as a gpio controller.
-- #gpio-cells     : Should be two. The first cell is the pin number and the
-                    second cell is used to specify the gpio polarity.
-
-See Documentation/devicetree/bindings/gpio/gpio.txt for further information on
-GPIO bindings.
-
-- interrupts : IRQ line information.
-- interrupt-controller
-
-See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
-further information on IRQ bindings.
-
-Sub-nodes:
-
-- regulators : This node defines the settings for the LDOs and BUCKs.
-  The DA9062 regulators are bound using their names listed below:
-
-    buck1    : BUCK_1
-    buck2    : BUCK_2
-    buck3    : BUCK_3
-    buck4    : BUCK_4

-    ldo2     : LDO_2
-    ldo3     : LDO_3

-
-  The component follows the standard regulator framework and the bindings
-  details of individual regulator device can be found in:
-  Documentation/devicetree/bindings/regulator/regulator.txt
-
-  regulator-initial-mode may be specified for buck regulators using mode values
-  from include/dt-bindings/regulator/dlg,da9063-regulator.h.
-
-- rtc : This node defines settings required for the Real-Time Clock associated
-  with the DA9062. There are currently no entries in this binding, however
-  compatible = "dlg,da9062-rtc" should be added if a node is created.
