All these consw::con_putc() implementations do the same as
consw::con_putcs() (only for one charattr) or even call
consw::con_putcs() on their own.

Drop them, as thanks to the new con_putc() helper in the previous patch,
the console code performs this already -- exactly if consw::con_putc()
is missing (NULL).
