Don't touch the pipestat regs for detecting FIFO underrun. The kernel owns them.
Since we don't perform any synchronization with the kernel on these regs, we
could race with the kernel to write stale values and end up not having vblank
interrupts enabled when somebody was waiting on one.
(cherry picked from commit 830bf916724afd21b7947f797c22a8c8aab7a0a4)
