[PATCH v4 5/7] dt-bindings: arm: rockchip: Add Engicam PX30.Core C.TOUCH 2.0

[Jagan Teki]

PX30.Core is an EDIMM SOM based on Rockchip PX30 from Engicam.

C.TOUCH 2.0 is a general purpose carrier board with capacitive
touch interface support.

PX30.Core needs to mount on top of this Carrier board for creating
complete PX30.Core C.TOUCH 2.0 board.

Add bindings for it.
