Add support for Pimoroni Hyperpixel 4.0

[philletourneau]

Hi Folks,

The Hyperpixel screens by Pimoroni are stunning.
See here: Shop Pimoroni Hyperpixel

The drivers can be found here:
Hyperpixel on github

I would love to see support for this LCD added to this WPE project. If I had the skills, I would do so myself, however this is a little over my head.
These screens have a very high pixel density, high-speed DPI interface for 60FPS, and capacitive touch. They make great touch-enabled control surfaces.

Can someone either point me in the right direction, or add support to this LCD to the project? Performant WebGL and this LCD would be a killer combination.

@philletourneau the hyperpixel screen, once configured, should work our of the box with balena-wpe. Apparently our raspberrypi images don't include the overlay by default, see balena-os/balena-raspberrypi#221. But in the meantime you can test this by adding the overlay in the overlays/ directory in the boot partition of your SD card and then enabling the right config.txt options through the balenaCloud dashboard
