dt-bindings: mfd: DA9062/61 MFD binding

Browse Source 
Extend existing DA9062 binding information to include the DA9061 PMIC for
MFD core and regulators.

Add a da9062-onkey link to the existing onkey binding file.

Add a da9062-thermal link to the new temperature monitoring binding file.

Delete the da9062-watchdog section and replace it with a link to the new
DA9061/62 binding information file.

* Dialog DA9062 Power Management Integrated Circuit (PMIC)
DA9062 consists of a large and varied group of sub-devices:

da9062-rtc : : Real-Time Clock
da9062-onkey : : On Key
