seshendra 07ddc5aaad gpu: nvgpu: Enabling/disabling FECS trace support ...

- To enable FECS trace support, nvgpu should set the MSB
of the read pointer (MAILBOX1).
- The ucode will check if the feature is enabled/disabled
before writing a record into the circular buffer. If the
feature is disabled, it will not write the record.
- If the feature is enabled and the buffer is not allocated,
HW will throw a page fault error.
