* Add a workaround-delay in Serial.flush()

In relation to #2536 and #2502

Tested at 80MHz and 160MHz with flash-frequency at both 40MHz and 80MHz, the bug mentioned in the above issues manifests in all cases. The proposed workaround seems to work fine, I tested at 2400bps, 9600bps, 115200bps, 230400bps and 2Mbps and didn't see anomalous output.

* Remove extraneous character

* Update HardwareSerial.cpp
