   powerpc: Remove unecessary VSX symbols

   The symbol THREAD_VSR0 is defined to be the same as THREAD_FPR0.  Its
   presence causes build issues with more complex configurations.

Can you explain what these "complex configurations" are?

In an earlier email we discussed the possibility that there was the
possibility/desire that a single binary could support either FPU, VSX
and the new QPX.  However, if a CONFIG_VSX is not defined then
THREAD_VSR0 does not get defined even though there might be some code
that refers to it.  Since it is an alias for the same piece of storage
I was hoping to solve my config issue and be simplify the code.

Yep, I remember the conversation.  I just want that explanation in the
commit log so others know *why* it was changed.
