lights: boot: use DSI panel regulator driver

Browse Source 
* Old rpi_backlight driver is no longer used on recent kernel versions.
  Regulator driver is used for backlight instead.
* Change the backlight path and implement scaling to support the official
  Raspberry Pi 7" DSI Touch Display & Touch Display 2.
* The original Touch Display has max brightness of 255 while the new Touch
  Display 2 has 31.
