gpu: host1x: Rewrite syncpoint interrupt handling Move from the old, complex intr handling code to a new implementation based on dma_fences. While there is a fair bit of churn to get there, the new implementation is much simpler and likely faster as well due to allowing signaling directly from interrupt context.

gpu: host1x: Add no-recovery mode Add a new property for jobs to enable or disable recovery i.e. CPU increments of syncpoints to max value on job timeout. This allows for a more solid model for hanged jobs, where userspace doesn't need to guess if a syncpoint increment happened because the job completed, or because job timeout was triggered. On job timeout, we stop the channel, NOP all future jobs on the channel using the same syncpoint, mark the syncpoint as locked and resume the channel from the next job, if any. The future jobs are NOPed, since because we don't do the CPU increments, the value of the syncpoint is no longer synchronized, and any waiters would become confused if a future job incremented the syncpoint. The syncpoint is marked locked to ensure that any future jobs cannot increment the syncpoint either, until the application has recognized the situation and reallocated the syncpoint.
