gpu: nvgpu: Read all fields of device_info
We were not using the engine_type field in device info, and the code
did not handle chained entries properly. The code assumed that first
entry is for graphics and second for CE, which is not always true.
Improve the code to go through all entries of device_info, and
preserve values across entries until we reach the last entry.
Only last entry triggers a write to fifo engine info.
There can also be multiple engines with same type, so accumulate
interrupts and reset ids from all of them.
As the code got fixed, now it reads the engine enum correctly from
hardware. We used to compare that against CE0, but we should compare
against CE2.
gk20a_fifo_reset_engine() uses wrong constants - it is passed a
internal numbering of engines, but it compares them against hardware
engine enum.
