[PATCH v3 5/7] target/ppc: removed VSCR from SPR registration |
Date: |

Since vscr is not an spr, its initialization was removed from the
spr registration functions, and moved to the relevant init_procs.
We may look into adding vscr to the reset path instead of the init
path (as suggested by David Gibson), but this looked like a good
enough solution for now.
