The superio needs 0x87 sent twice to 0x3f0 to enable extended function
(power-on strapping). Although this is already done in superio.c, it's
not being done when w83977tf_early_serial.c is executed. As such, no
console_init -- atleast in my case.
(Next on the agenda, check the other winbond superio chips to see if
this is needed as well as I have the chip spec pdf files here as well.
I noticed the other winbond chips use different addresses and values.)
