target-ppc: remove powerpc 970gx

The 970GX definition was added in 2007 and it made sense then but this version has never been released to the markets and it does not exist in the real world so there is no point in emulating it. This removes 970GX. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>
