Tabakhase 653b4bae03 clearify rpi_gpio sharing + revert #4608 (#4660)
* Revert "add documentation for "shared_gpio" flag to component switch.rpi_gpio"

This reverts commit f2dba1f614af51f84eadbdeab5ca2f566f334ad6.

* clearify that rpi_gpio pins are exclusive to HASS-ussage when assigned

The `rpi_gpio` switch platform allows you to control the GPIOs of your [Raspberry Pi](https://www.raspberrypi.org/).
To use your Raspberry Pi's GPIO in your installation, add the following to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
switch:
- platform: rpi_gpio
ports:
11: Fan Office
12: Light Desk
```
Configuration variables:
- **ports** array (*Required*): Array of used ports.
- **port: name** (*Required*): Port numbers and corresponding names (GPIO #).
- **invert_logic** (*Optional*): If true, inverts the output logic to ACTIVE LOW. Default is false (ACTIVE HIGH).
For more details about the GPIO layout, visit the Wikipedia [article](https://en.wikipedia.org/wiki/Raspberry_Pi#GPIO_connector) about the Raspberry Pi.
<p class='note warning'>
Note that a pin managed by HASS is expected to be exclusive to HASS.
</p>
A common question is what does Port refer to, this number is the actual GPIO # not the pin #.
For example, if you have a relay connected to pin 11 its GPIO # is 17.
```yaml
# Example configuration.yaml entry
switch:
- platform: rpi_gpio
ports:
17: Speaker Relay
```
