Benoît Thébaudeau a52a3d94d3 cc2538: uart: Fix garbled output occurring upon lpm_enter()
lpm_enter() must not enter PM1+ if the UART is transmitting. Otherwise,
the UART clock gets disabled, and its TX is broken.

The commit b8b54a033c had already
partially fixed this issue, but it could still occur while transmitting
stop bits because, contrary to UART_FR.BUSY, UART_FR.TXFE takes only the
data bits into account, not the stop bits.

George Oikonomou 568973f6ec Don't flush the CC2538 RF RX FIFO unconditionally
After reading a frame, `read()` checks the status of the RX FIFO:

* If an overflow is detected, the FIFO gets flushed
* If there are more frames in the FIFO, the `cc2538_rf_process` will get polled again in order to read out the next frame.

#1550 changed `read()`, which now performs the above check for non-poll mode, but it then flushes the FIFO unconditionally. Therefore, if there are two or more frames in the FIFO, they will get flushed before the `cc2538_rf_process` has had a chance to read them out. This results in missed frames.

Reproducing this is trivial: Build a CC2538 sniffer and see how it will never show you .15.4 ACK frames. ACK reception completes while `read()` is still streaming the previous captured frame to the host. Upon completion, the FIFO will get flushed and the ACK will get lost.

This pull proposes removing the unconditional flush and reverting to the original logic for non-TSCH operation.

Pinging @thomas-ha here for input regarding poll mode.

This pull sits on top of #1778

Benoît Thébaudeau 1da00a482f cc2538: aes: Fix possibly missing result available status
Depending on the use case and on the timings,
aes_auth_crypt_check_status() sometimes never reported an available
result, leading to a deadlock of any protothread waiting for this event,
and to a WDT reset if a protothread was polling it.

This was caused by aes_auth_crypt_start() clearing the result available
interrupt after operations that may rightfully trigger it, leading to a
missed interrupt.
