platform/x86: x86-android-tablets: convert Goodix devices to GPIO references

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

Since the tablets are using either Baytrail or Cherryview GPIO
controllers x86_dev_info structure has been extended to carry gpiochip
type information so that the code can instantiate correct set of
software nodes representing the GPIO chip.

Because this adds a new point of failure in x86_android_tablet_probe(),
x86_android_tablet_remove() is rearranged to handle cases where battery
swnode has not been registered yet, and registering of GPIO lookup
tables is moved earlier as it can not fail.
