ARM: dts: overlays: waveshare-panel-v2: Add 6.25-DSI-TOUCH-A overlay

Add device tree overlay entries for the Waveshare 6.25-DSI-TOUCH-A

display in both 2-lane and 4-lane configurations.

The 6.25-DSI-TOUCH-A uses the Sitronix ST7123 touchscreen

controller at I2C address 0x55, replacing the default Goodix

touch configuration.

Rename the touch node from goodix@5d to touch@5d to reflect

that different panels may use different touch controllers.
