Try to fix invalid pte type repalayable faults only.
All other replayable faults will be cancelled so that
next mmu fault for same fault address will be triggered
as non-replayable fault and ch/tsg teardown will take place.

Add new API gv11b_fifo_tsg_verify_status_faulted() and use that as
g->ops.fifo.tsg_verify_status_faulted operation for gv11b/gv100
This API will check if channel has ENG_FAULTED status set, if yes it will clear
CE method buffer in case saved out channel is same as faulted channel
We need to write 0 to method count to invalidate CE method buffer
Also set g->ops.fifo.tsg_verify_status_ctx_reload operation for gv11b/gv100

Added handling for below ce interrupts
-INVALID_CONFIG interrupt will be generated if a floorswept
PCE is assigned to a valid LCE in the NV_CE_PCE2LCE_CONFIG
registers. This is a fatal error and the LCE will have to be
reset to get back to a working state.
-MTHD_BUFFER_FAULT interrupt will be triggered if any access to
a method buffer during context load or save encounters a fault.
This is a fatal interrupt and will require at least the LCE to be reset
before operations can start again, if not the entire GPU.
