[LinuxBIOS] Patch for w83977tf to enable early_serial

[roger]

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.)
