gpu: nvgpu: add profiler apis to manage PMA stream

Browse Source 
Support new IOCTL to manage PMA stream meta data by adding below API
nvgpu_prof_ioctl_pma_stream_update_get_put()

Add nvgpu_perfbuf_update_get_put() to handle all the updates coming
from userspace and to pass all required information.

Add gops.perf.update_get_put() to handle all HW accesses required in
perf HW unit.

Add gops.perf.bind_mem_bytes_buffer_addr() to bind the available bytes
buffer while binding HWPM streamout.
