Subject: [PATCH] dtoverlays: Add overlays for Pimoroni Hyperpixel
displays
Adds an overlays for the Pimoroni HyperPixel4, HyperPixel 4
Square, and HyperPixel 2 Round DPI displays.
We have a conflict over the use of GPIO 27 for touch screen
interrupt and SPI CLK for configuring the display on the
two HyperPixel4 displays.
