Use volatile register access for gpio interrupts (#170) 
* Use volatile register access for gpio interrupts

* Provide functions for atomic register updates

* Use atomic register access functions in pio.rs

* Improve doc comments

* Limit visibility of atomic register access functions

Also remove write_xor for now, as it's not yet used anywhere

PIO support (#74) 
Initial implementation of PIO 

Add all of the infrastructure required to include PIO programs and interact with PIO peripheral registers.
This was a massive effort between @devsnek and @henkkuli. It's great that it's now ready to go.

Andrea Nall e3be4f8025 Massive GPIO refactor 
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.

Andrea Nall 8d0fde20c6 Add SubsystemReset trait to handle subsystem resets 
dd a `SubsystemReset` trait which adds a `reset_bring_up` function to the
relevant PAC types to handle bringing subsystems out of reset.

Also, correct that the PLL and UART modules did not bring the relevant
subsystems out of reset and refactor the GPIO module to use the
SubsystemReset trait.
