add 'togglePin' convenience function (#8734)
* add 'togglePin' conveniance function for AVR and chibios * drop outmost parantheses Co-Authored-By: Konstantin Đorđević <vomindoraan@gmail.com> * toggle pin on avrs toggle a pin configured as output by writing the corresponding bit to the PIN register Co-Authored-By: Takeshi ISHII <2170248+mtei@users.noreply.github.com> * togglepin: add documentation for newly added function * Update docs/internals_gpio_control.md Co-Authored-By: Konstantin Đorđević <vomindoraan@gmail.com> * on AVR: use PORTD to toggle the output ... since not all MCUs support toggling through writing to PIN Co-Authored-By: Ryan <fauxpark@gmail.com> Co-authored-by: Johannes <you@example.com> Co-authored-by: Konstantin Đorđević <vomindoraan@gmail.com> Co-authored-by: Takeshi ISHII <2170248+mtei@users.noreply.github.com> Co-authored-by: Ryan <fauxpark@gmail.com>
