gpu: nvgpu: Change in pstate s/w setup sequence

Browse Source 
pstate s/w setup needs to know offsets of boardobjs present
in PMU super surface to construct boardobj set/get_status
construct.

With SSMD support, boardobj offset will be part of SSMD
lookup table which is part of PMU super surface buffer &
updated by PMU RTOS during init stage.

As SSMD is updated at init stage & SSMD will be ready for nvgpu
to read offsets only when PMU init message is received,
so pstate s/w must wait till PMU is ready to construct
boardobj set/get_status
