Fix incorrect maximum PS thread count on IvyBridge
I mistakenly set GEN7_PS_MAX_THREAD_SHIFT to 23; it's actually 24 on
Ivybridge. Not only did this halve our thread count, it caused us to
write 1 into a bit 23, which is marked as MBZ (must be zero).
Furthermore, it made us write an even number into this field, which is
apparently not allowed. Apparently we were just lucky it worked.
