[COMMIT] Infrastructure Updates 4

[YhLu]

Eric,

In the hypertransport_scan_chain, if the hard_reset is needed, it may
produce problem.

Hard_reset call 8111 LPC (B1, D4, F0) reg 0x47 to trigger Reset.

But it is called before pci_scan_bus. At that time the 8111 LPC is still
unkown.

Regards

YH

I still have problems for s2885.

Amdk8_scan_bus for MC0 only from link0 to link2.  link0 is connected to 8151
and link2 is connected to 8131.

Then it reboot again and agin.

After I reverse the scan from link2 to link0. It can scan out 8131 and 8111
but hung after "HyperT reset needed" is printed. Maybe the reset.c that I
move from hdama got some problems.
