Add a device tree for the Samsung Galaxy Tab 4 10.1 (SM-T530) wifi tablet based on the apq8026 platform. Currently supported are accelerometer sensor, hall sensor, internal storage, physical buttons (power & volume), screen (based on simple-framebuffer set up by the bootloader), sdcard, touchscreen and USB.
