gpu: nvgpu: Update debug crash dump

Browse Source 
Update the debug crash dump to be clearer, more concise and
avoid many of the misformatting issues that have crept in over
the last couple years.

This also changes the debug prints to move from pr_err() in
the Linux kernel to nvgpu_err(). This makes it easier to
filter all nvgpu messages in a log file with a single grep
command.
