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

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