Winbond W83627HF: Use existing functions instead of open-coding.

Use w83627hf_set_clksel_48() where needed instead or open-coding the same
functionality, and also use w83627hf_enable_serial() instead of 
w83627hf_enable_dev() (which does exactly the same, but isn't wrapped in the
enter/exit config mode functions).

Abuild-tested.
