4fd831e4a8 rp async i2c: raise the tx_empty threshold 
Assert "tx_empty" interrupt a little early so there's time to wake up
and start refilling the fifo before it drains. This avoids stalling the
i2c bus if the tx fifo completely drains.

cae8499179 rp i2c: clean up tx_abrt handling 
Make sure we always wait for the stop bit if there's a reason to -
either because we sent one, or because there was a hardware tx abort.

5e2c52ee5b embassy-rp: async i2c implementation 
This is an interrupt-driven async i2c master implementation. It makes as
best use of the RP2040's i2c block's fifos as possible to minimize
interrupts.

It implements embedded_hal_async::i2c for easy interop.
WIP async impl

90d392205f embassy-rp: inline I2c::regs 
It just returns a literal constant, so there's no reason not to always inline it.

Merge #972 
972: Restructure USB crates r=Dirbaio a=Dirbaio

- Split driver from `embassy-usb` to a separate crate. This allows making breaking changes to `embassy-usb` without having to bump all the crates with driver impls, such as HALs.
- Merge classes into `embassy-usb`. Now that breaking changes to `embassy-usb` aren't that bad, having everything in a single crate is much easier.

8ba421f324 Do not use cfg_if for embedded-hal-async feature gates. 
Old code used `cfg_if!` because rustc still parses code inside disabled cfg's, and Rust stable at that time couldn't parse the new GAT where-clause location. This is not the case anymore.
