Document a "reset" and "assert-reset-us", it can be used for
driver control reset property. And reuse post-power-on-delay-ms

If there was any point in adding the device-specific description
around "wacom,w9013"...then you should probably mention these
properties there too. The idea was to document possible properties
here (where you're adding them already), and to note the property
names under the devices (or so far, just 1 device) that support them.
Or IOW, you need an addition like this:
- compatible:
* "wacom,w9013" (Wacom W9013 digitizer). Supports:
- vdd-supply
- post-power-on-delay-ms
+ - reset-gpios
+ - assert-reset-us
Okay, got it, will fix it next version.
