ARM: dts: qcom: Add support for Samsung Galaxy Tab 4 10.1 (SM-T530)

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.
