ITE IT8661F changes to match the common code structure.
- it8661f_enable_serial() is now in the usual format, using pnp_* functions.
- Factor out pnp_enter_ext_func_mode()/pnp_exit_ext_func_mode().
- Factor out it8661f_set_clkin() to set the CLKIN to 24/48MHz.
- Factor out it8661f_enable_logical_devices(), might not be needed though.
We leave it here until it's confirmed on hardware that it's not needed.
- Move some #defines to it8661f.h.
- Drop no longer used it8661f_sio_write().
