Sagar Kamble 84b493e644 gpu: nvgpu: update SEC2 falcon base addr init
SEC2 falcon base address was being set without invoking hal api. Remove
FALCON_SEC_BASE. This patch defines gpu_ops.sec2.falcon_base_addr hal api
to get this base address.
Also, don't initialize the base for non-supported falcons.
