drivers/console: xtensa_sim_console: implement arch_printk_char_out()

Browse source 
This is an older driver and didn't support the weak
arch_printk_char_out() hook, which is a link-time symbol that allows
logging to work from the first instruction.  Some drivers can't do
that because they need an initialization step, but this one works
great.
