nvgpu: gpu: Add boot pstate index in Pstate boardobj

In the change_seq of latest ucode, the boot pstate
index was taken from pstate board_objs instead of the
value from change_input. This forces the need of
introducing boot index in pstate board_obj structure.
The index is the performance table entry index of
P0 pstate.

The ucode change is described in P4CL #27304645
