Add the Heltec v4 expansion box. (#8539)

* Add the Heltec v4 expansion box.

* Change heltec-v4-oled to heltec-v4.

* Add touchscreen to I2C scanning.

* Add reset and busy pins to the ST7789.

* Ignore the touch interrupt pin and extend the sleep time to 1 hour.

* Remove the default sleep function.
