David Engraf cb47b9f863 tty/serial: atmel: fix out of range clock divider handling
Use MCK_DIV8 when the clock divider is > 65535. Unfortunately the mode
register was already written thus the clock selection is ignored.

Fix by doing the baud rate calulation before setting the mode.

Fixes: 5bf5635ac1 ("tty/serial: atmel: add fractional baud rate support")
