Implement bus keep inputs, as documented in C SDK (#134)
When both pull-up and pull-down are enabled, the RP2040 enters a
so-called "bus keep" function, which uses a weak pull to tue current
high/low state of the GPIO.

See for example
https://raspberrypi.github.io/pico-sdk-doxygen/group__hardware__gpio.html#gab6bf9552da32b3dd0a5d0db45d8374fc

Implement RngCore for RingOscillator (#135)
Implement rand_core::RngCore for RingOscillator from the get_random_bit
function. This is not suitable for security purposes so
rand_core::CryptoRng has not been implemented.

Add unsafe blocks around write_with_zero calls (#68)

Improve clock frequency stuff for uninitialized clocks and add some examples (#64)
* Improve clock frequency stuff for uninitialized clocks

- Made clocks singletons so the frequency handling actually works as expected
- Added initial frequencies
- Improved the docs
- Added a Clock trait

* Add pico examples.

These have the benefit of knowing which external crystal is attached.
Even though it always should be a 12 MHz crystal.
Thus we can setup the clocks properly

I also changed the rp2040 examples to work out of the box for pico boards since that will probably be used most of the time

subsystems out of reset and refactor the GPIO module to use the
SubsystemReset trait.
