rp: Improve BufferedUart interrupt handling
...
* Only clear interrupt flags that have fired (so that we do not lose any error flags)
* Enable RX interrupt when a read is requested, disable it when the RX buffer is full
* Rework TX interrupt handling: its "edge" triggered by a FIFO threshold

rp: Disable RX interrupts when ring buffer is full
...
When data is in the RX fifo the RX timeout interrupt goes high again even after clearing it.
The result is a deadlock because execution is stuck in the interrupt handler. No other code
can run to clear the receive buffer.
Enable and disable RX interrupts based on the buffer fill level.
Use the same approach for the TX code path.

rp: Fill and empty FIFOs in buffered uart interrupt
...
Fixes an issue where only the first byte was transmitted.
Should improve throughput aswell.
