gpu: nvgpu: configure CWD sm id regs before ucode load

Browse Source 
GPCCS ucode is expecting the SM ID programmed in GPM and CWD registers
to be in sync. So create a hal called gr.init.load_sm_id_config()
for the sm_id programming for the CWD registers and invoke them before
the ucode load.

Initialize this hal only for the required GPUs.
