Subject: [PATCH v2 08/11] platform/x86: x86-android-tablets: convert HID-I2C devices to GPIO references

Now that gpiolib supports software nodes to describe GPIOs, switch the
driver away from using GPIO lookup tables for HID-I2C touchscreens to
using PROPERTY_ENTRY_GPIO() to keep all touchscreen properties together.
