[intel] Get vblank pipe from irq_mask_reg instead of hardware enable reg
With the interrupt enable/disable using only the mask register, it was wrong to use the enable register to detect which pipes had vblank detection turned on. Also, as we keep a local copy of the mask register around, and MSI machines smack the hardware during the interrupt handler, it is more efficient and more correct to use the local copy.
