Subject: [PATCH v2 02/11] platform/x86: x86-android-tablets: convert Wacom devices to GPIO references

Now that gpiolib supports software nodes to describe GPIOs, switch the
driver away from using GPIO lookup tables for Wacom touchscreens to using
PROPERTY_ENTRY_GPIO() to keep all touchscreen properties together.
