Subject: [PATCH v2 05/11] platform/x86: x86-android-tablets: convert EDT devices to GPIO references

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