mkumbar 87984ea344 gpu: nvgpu: support nvriscv debug feature
Enable nvriscv debug buffer feature in NVGPU.
Debug buffer is a feature to print the debug log from ucode onto console
in real time.
Debug buffer feature uses the DMEM, queue and SWGEN1 interrupt to share
ucode debug data with NVGPU.
Ucode writes debug message to DMEM and updates offset in queue to trigger
interrupt to NVGPU.
NVGPU copies the debug message from DMEM to local buffer to process and
print onto console.

Debug buffer feature is added under falcon unit and required engine
can utilize the feature by providing required param through public
functions.

Currently GA10B NVRISCV NS/LS PMU ucode has support for this feature
and enabled support on NVGPU side by adding required changes, with this
feature enabled, it is now possible to see prints in real time.
