Remove duplicate code from HardwareSerial::begin() methods.
There are two begin methods, one which accepts just a baud rate and uses the default bit settings and one which accepts both a baudrate and a bit config. Previously, both of these contained a complete implementation, but now the former just calls the latter, explicitely passing the default 8N1 configuration. Technically, this causes a small change: Before the UCSRC register was untouched when calling begin(baud), now it is explicitely initialized with 8N1. However, since this is the default configuration for at least the Uno and the Mega (didn't check any others), probably for all avrs, this shouldn't effectively change anything. Given that the Arduino documentation also documents this as the default when none is passed, explicitly setting it is probably a good idea in any case.
