ARM: dts: msm: Enable CVP SMMU fault tolerance and Stall disable

Browse source 
"non-fatal" -> smmu will not bug_on for s1 fault.
Avoid system crash when CVP SMMU fault happens.
CVP SSR can recover SMMU fault now
"stall-disable" -> smmu terminates pending transaction
Invokes smmu_fault_handler and triggers vnoc interrupt
independently. So firmware can quickly write sys_error
pkt(previous transactions were not stalled for that CB)
to message queue.
