Support for m5dial touch driver

**Describe the problem you have/What new integration you would like**
The m5dial uses a GC9A01 screen with a FT3267 touch driver. I have been able to integrate the display using an external component, but not the touchscreen.

**Please describe your use case for this integration and alternatives you've tried:**
I have tried external components with used for other devices with GC9A01 based screens (like the ones with CST816S series touchscreens), but have not had any luck registering touch events.

**Additional context**
Details of the m5dial are here, including pinouts and other details
