tty/serial: atmel: fix out of range clock divider handling
commit cb47b9f8630ae3fa3f5fbd0c7003faba7abdf711 upstream.
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: 5bf5635ac170 ("tty/serial: atmel: add fractional baud rate support")
