ppc64: Fix clobber list item for JUMP_TO_RESTORER_BLOB

Browse source 
The JUMP_TO_RESTORER_BLOB assembly macro has been rewrote through the
commit '89d6b39cfe ppc64: pie -- Add ppc64le relocation's
processing', but the Clobber list hasn't been updated.

This doesn't generate build neither runtime errors since the Clobber
list was larger than needed but GCC 7 is now raising an error when an
assembly macro is clobbering the r2 register.

This patch fix the Clobber list to just modified registers.

Fixes: 89d6b39cfe ("ppc64: pie -- Add ppc64le relocation's processing")
