Anton Staaf 014d180b1d USART: Split RX driver between L and F families
The USART peripheral in the L and F families is different enough to need
different receive drivers.  In particular, the L family USART perihperal
has no way of disabling the overflow error bit.  So for that family we
check and clear the bit, and keep a count of overflows.
