gpu: nvgpu: hwpm broadcast register support

Add support for hwpm broadcast registers (ltc and lts)

In gr_gk20a_find_priv_offset_in_buffer, replace "Unknown address type" error
with informational message: gr_gk20a_exec_ctx_ops calls
gk20a_get_ctx_buffer_offsets and if that fails,
calls gr_gk20a_get_pm_ctx_buffer_offsets; HWPM registers will fail the first
call, so an error or warning is overkill.

Bug 1648200
