The Waveshare DSI TOUCH family of DSI panel kits feature different DSI
video-mode panels, bundled with the separate controlling circuit,
produing necessary voltages from the 3.3V and 5V supplies. Extend panel
drivers to support those Waveshare panels and also add GPIO driver for
the onboard control circuitry.

Changes in v2:
- Fixed errors in focaltech,ota7290b and waveshare,dsi-touch-gpio schemas
- Split the JD9365 patch, making the changes more obvious (and
  describing panel classes)
- Cleaned up GPIO driver: moved NUM_GPIOS from the enum, switched to
  guard(), added regmap error handling, dropped
waveshare_gpio_i2c_read() (Bartosz)
- Link to v1: https://patch.msgid.link/20260401-waveshare-dsi-touch-v1-0-5e9119b5a014@oss.qualcomm.com
