Previously this was only defined for CPU_MONAHANS.
If this really is a common register, add a comment to
the commit log.

Be aware that the preferred method of register access
is through structure member elements.  In this case,
this is a trival change so I do not believe converting
the access is warranted.  But it will likely be in the
future.

For readability, change the tab after #define to a space.
This is an issue in the 2/2 patch as well
