Input: da9062 - update bindings docs to account for da9061

Add binding information for DA9061 onkey.

This patch updates the compatible string "dlg,da9061-onkey" to support
DA9061, removes the reference to KEY_SLEEP (which the driver no longer
supports) and fixes a typo in the example for DA9063.

Supporting KEY_SLEEP was not the general convention and the typical
solution should have been for KEY_POWER to support both cases of suspend
and S/W power off. This change was sent to the DA9063 ONKEY device
driver in a separate patch, but the documentation was not updated at
that time.
- f889bea Report KEY_POWER instead of KEY_SLEEP during power key-press

This patch also adds two new examples, one for DA9062 and one for DA9061.
The DA9061 examples uses a fall-back compatible string for the DA9062
onkey driver.

 Required properties:
 
-- compatible: should be one of:
-       dlg,da9062-onkey
-       dlg,da9063-onkey
+- compatible: should be one of the following valid compatible string lines:
+       "dlg,da9061-onkey", "dlg,da9062-onkey"
+       "dlg,da9062-onkey"
+       "dlg,da9063-onkey"

-  - dlg,disable-key-power : Disable power-down using a long key-press. If this

     entry exists the OnKey driver will remove support for the KEY_POWER key
-    press. If this entry does not exist then by default the key-press
-    triggered power down is enabled and the OnKey will support both KEY_POWER
-    and KEY_SLEEP.
+    press when triggered using a long press of the OnKey.
