bit 10 is part of NewVID. That means the resulting VID is wrong and
causes the processor to crash.
The Pistachio code has the same bug.
This patch fixes the wrong setting and changes control from a magic and
incorrect unexplained value (0xE8202C00) to a combination of explained
values and shifts which has the right value (0xE8202800).
It is tested on my machine and it survived 200 changes from minimum to
maximum frequency every 100 ms under heavy load and under no load.
In the long term we want to consolidate all AMD FIDVID code into one
generic library file.

Maggie Li has tested it on her DBM690T board. It is ok.

revF CPUs. The 100MHz/200MHz stepping is already handled in the FID setting
and doesn't need to be checked to set the fid_multiplier. The multiplier is
always 100.
