drm/i915: Mask everything in ring HWSTAM on gen6+ in ringbuffer mode
The execlist code already masks everything in the ring HWSTAM, but
the ringbuffer code doesn't. Let's go ahead and do that. Pre-gen6
platforms setup HWSTAM during irq setup already since there's just
the one register, and it also contains bits for non-ring interrupts.
