platform/x86: x86-android-tablets: Add support for the Dolby button on Peaq C1010

The Peaq C1010 tablet has a special "Dolby" button. This button has
a WMI interface, but this is broken in several ways:

1. It only supports polling
2. The value read on polling goes from 0 -> 1 for one poll on both edges
   of the button, with no way to tell which edge causes the poll to
   return 1.
3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID).

There currently is a WMI driver for this, but it uses several kludges
to work around these issues and is not entirely reliable due to 2.

Replace the unreliable WMI driver by using the x86-android-tablets code
to instantiate a gpio_keys device for this.
