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.

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