Tejal Kudav 90f268963c gpu: nvgpu: Correct the device info table parsing ...

We parse the DEVICE_INFO table entries to get IOCTRL(NVLINK)
engine related information like the pri_base_addr, reset_enum,
and the intr_enum.

For grouping the chained entries per IP, the current parsing logic
relies on the fact that engine_type entry for an IP will be parsed
before other entries in the chained group.
As the enum_type entry (which contains the reset_enum) appears
ahead of the engine_type entry, the parsing logic fails and we read
reset_enum as 0.
Modify the parsing logic to group the chained entries correctly.

Also we were using a wrong API to extract the reset/intr_enum from the
table entry.
