Blindly writing the default configuration value into the SCSCR register
may change the clock selection bits, breaking the serial console if the
current driver settings differ from the default settings.
Keep the current clock selection bits to prevent this from happening

sci_port.sampling_rate is always non-zero, except for HSCIF, which uses
sci_baud_calc_hscif() instead of sci_scbrr_calc().

Yup, that seems like a more suitable base.
