fix: Fix for async I2C v2 driver sequential read/write reads. Fixes #3887
For I2C devices that support variable length reads, sending chunks of data as long as the master keeps ACK:ing after each received byte, sequential reads will sometimes get out of sync, causing additional reads to return invalid data.
This was caused by a delay between awaiting the DMA read and sending the software STOP signal, which may result in the slave to have time to send a byte of data in between, causing potential miss-alignment. This would then cause subsequent reads to return invalid data.
Async write-reads now no longer send STOP after the initial write, matching the behaviour of the blocking version.
