[LinuxBIOS] bad value in HT UnitID Registers

[Lu, Yinghai]

default HT_CHAIN_UNITID_BASE=0

is used when your ht chain only have one ht device. And you can use
unitid base 0.

The reason is some time ago, if you change CK804 unitid, you will lose
the bus master feature of it.

This is tricky. Thank you.
I still do not understand the point of "default HT_CHAIN_UNITID_BASE=0".

I wish this were implemented in a more generic way which works in all
N-way
motherboards.
