rp i2c: have separate wakers for each i2c unit
...
If they both share one waker, there's the possibility that some wakeups
could get lost.

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.

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.

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.

embassy-rp: inline I2c::regs

It just returns a literal constant, so there's no reason not to always inline it.
