Deepak Nibade c6aae8c049 gpu: nvgpu: use fixed address mapping for pma byte buffer ...

Use fixed address mapping for pma byte buffer so that the address of
this buffer always fits in 32 bits.

This also requires to move unmap sequence to OS specific function since
different unmap API is now needed for linux and QNX.

Also call nvgpu_prof_free_pma_stream_priv_data() before
nvgpu_profiler_free_pma_stream() since former uses mm->perfbuf which
is released in later.
