01eb416745 gpu: nvgpu: gsp sched: enable gsp sw init for safety build 
Changes
1. Remove dGPU flag dependency on calling gsp sw init on tot.
2. Created Enable flag for gsp scheduler to enable them on ga10b
platforms.
3. Engine config flag is only enabled for dGPU enabled platforms, as gsp
is using engine functions it need to be enabled for all gsp sched
enabled builds.
4. Changes in gsp_sequence_init/de_init where on qnx we are seeing
issues.

4a7e5056a5 gpu: nvgpu: disable gsp isr on suspend 
nvgpu_gsp_sw_deinit() is called so late that the GPU HW is not expected
to be available, so it must not call nvgpu_gsp_isr_support(). Move that
call to nvgpu_prepare_poweroff().

The gsp isr is still enabled in gsp bootstrap as before.
