[Qemu-ppc] [PULL 06/50] sysemu: support up to 1024 vCPUs

[David Gibson]

From: Greg Kurz <address@hidden>

Some systems can already provide more than 255 hardware threads.

Bumping the QEMU limit to 1024 seems reasonable:
- it has no visible overhead in top;
- the limit itself has no effect on hot paths.
