amd 8111 smbus controller definitions

[ron minnich]

Where are these:

#define SMBGSTATUS 0xe0
#define SMBGCTL    0xe2
#define SMBHSTADDR 0xe4
#define SMBHSTDAT  0xe6
#define SMBHSTCMD  0xe8
#define SMBHSTFIFO 0xe9

defined, i.e. what book? The 8111 book is self-contradictory and sketchy. 
Pointers welcome.
