Jan Niehusmann 402b7f1eb8 Use u32 instead of u64 division in clock calculations
This saves about 1kB of flash by removing
compiler_builtins::int::specialized_div_rem::u64_div_rem if
no other code uses u64 divisions.

Implement peripheral support for i2c and an advanced example (#162)
* Implement peripheral support for i2c and an advanced example for the pico board.

* Simplify i2c peripheral bootstrap and add a "free" function to allow switching modes.

* Set dependency to futures & nostd_async to specific version/revision.

* move enum & struct to the start of the file

* Add a bit of documentation to the pico_i2c_controller_peripheral demo.

* Migrate to pico_i2c_controller_peripheral to embassy & simplify the peripheral support

nostd_async is broken since last stable roll out.
The pico_i2c_controller_peripheral is being migrated to use embassy's executor.
The Controller Async API is now aligned with embassy's traits to facilitate integration.

The peripheral no longer require async to run and now appears as an event iterator.

Embassy's support relies on unstable features (generic_associated_types and type_alias_impl_traits)
and is therefore gated behind the `embassy-traits` feature flag.

* make futures & embassy optional for the pico board too

* Pin embassy to a specific rev.

* Impl embassy_traits::i2c::WriteIter & enable unlimited transfer size on i2c

* Applies comment suggestion from @9names for the advanced i2c example.

Co-authored-by: 9names <60134748+9names@users.noreply.github.com>

* use `I2C block` instead of `IP`.

* Fix formatting (unnecessary space at end of line)

* Enhance explanation for why `rd_req()`  is not cleared in `Iterator::next`'s
implementation.
