Bring in line with atsamd-hal GPIO v2 Copied as much as possible. Docs lifted mostly as-is. Also add sample BSP for the Feather RP2040 in boards/feather_rp2040 May include a few random fixes from currently futile attempt to get doctests working.

//! Toggle LED based on GPIO input
|
|
//!
|
|
//! This will control an LED on GP25 based on a button hooked up to GP15. The button should be tied
|
|
//! to ground, as the input pin is pulled high internally by this example. When the button is
|
|
//! pressed, the LED will turn off.
