VMI_CMD_xx Functions and GHI_CMD_xx Functions

There are only a few differences between the VMAN protocol, Video Manager 
Interface (VMI), and the GRADD protocol, Graphics Hardware Interface 
(GHI). In fact, the majority of the functions are identical, with only the 
prefix (VMI or GHI) indicating to which component the function belongs. 

The common functions are as follows:

Note:  The VMI_CMD_QUERYCHAININFO function has no corresponding GHI 
       function.
