ARM: dts: rockchip: Add missing the touchscreen interrupt on rk3288-phycore-rdk

According to the phyCORE - RK3288 Hardware Manual, GPIO5_B4 corresponds to
the touchscreen interrupt line:

https://www.phytec.eu/fileadmin/legacy/downloads/Manuals/L-826e_1.pdf

Describe it to improve the devicetree representation.

This fixes the following dt-schema warning:

	'interrupts' is a required property
	'interrupts-extended' is a required property
