Additional context

Hi !

I'm using the Lilygo EPD47 with the touchscreen.
In deep sleep, i've a 5.7mA power consumption : too high.

If i used the demo code and compile with Arduino IDE, the power in deep sleep is 380uA ... much better.

If i move all the C code (founded in demo code) used for the deepsleep in a Lambda, i'm stuck with the line making the touch screen sleeping : touch.sleep();
There's no sleep() method implemented in GT911 driver for ESPHOME

So, i think that in ESPHOME, the deep sleep of this board is not total for the touch screen.

In GT911 for Arduino it's :

 void sleep()
    {
        writeRegister(GT911_COMMAND, 0x05);
    }

Is it possible to add this to the GT911 driver ?

Thanks.
