tkudav cb8003d9e0 gpu: nvgpu: Modify common.top for better coverage ...

Following changes are done to common.top code and UT:

1.Change return type for device_info_parse_enum to void as it can never
return non-zero value.
   - This is a private HAL and is only called by get_device_info HAL.
   - It gets called only for table entry with entry type = enum.
   - So there is no error path left.
This helps remove unnecessary branches and get better branch coverage

2. Check if the data parsing function pointers are not NULL before
parsing the device tree. Return error if there are no functions
to interpret the device_info table registers. Add checks for same in
unit test test_get_device_info().
