[PATCH] PPC64: Trivial Cleanup: EEH_REGION

[Linas Vepstas]

Hi Paul, 

Please forward upstream if you agree.

This is a dumb, dorky cleanup patch:
Per last round of emails, the concept of EEH _REGION is gone, 
but a few  stubs remained.  This patch removes them.

Note there is some funny business in the SLB code that 
I did not understand, and so I left that alone.  
I'm guessing that it should be cut out as well.
