This CL covers the following modification,
1) Added multiple engine_info support
2) Added multiple runlist_info support
3) Initial changes for ASYNC CE support
4) Added ASYNC CE interrupt handling support
for gm206 GPU family
5) Added generic mechanism to identify the
CE engine pri_base address for gm206
(CE0, CE1 and CE2)
6) Removed hard coded engine_id logic and
made generic way
7) Code cleanup for readability

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.

New members are added in nvgpu_gpu_characterstics to export more
information required specially from CUDA tools.

Query interrupt number and reset id from HW. Use the number
from HW when enabling and detecting interrupts.
