uarte: Low power wait for RX drop

uarte: Wait for the peripheral to be disabled
...
Prevents a panic in the case of:
1. Abort a receive future
2. Free Uarte::free()
3. Uarte::new()
-> panicked at 'assertion failed: uarte.enable.read().enable().is_disabled()'

uarte: Enable peripheral with first poll
...
This fixes a lockup when a future is dropped before it was polled.

uarte: Be on safe side with potentially racy code
...
The PS does not specify how many cycles it takes for a STARTXX task to
generate a XXSTARTED event. I think it is instantaneous but let’s be on
the safe side for the following sequence:
1. poll() starttx
2. drop() txstarted not yet set, but future gets dropped
3. txstarted set by hardware, peripheral enabled after it was dropped

uarte: Only stop TX forcefully when a transmissions is running
...
This comes with insignificant power consumption improvements but makes
the code of the RX and TX case symmetric.

uarte: Only stop RX forcefully when a reception is running
...
The STOPRX task always triggers a timeout of ~55bit times until the
RXTO event is generated. Before we disabled the receiver only after
the timeout.
With this change the receiver is stopped right after reception has ended
because the DMA buffer is full.
For forced RX aborts like `stop()` or on drop still need to wait for the
RXTO event before disabling the receiver.

uarte: Do not spin when stopping a receive future
...
Spinning on drop() is still required when the future has not been
stopped so that DMA finishes before the buffer is released.
