gpu: nvgpu: fix recursion in included headers

We have this recursion in headers as pointed
by Coverity
gk20a/gk20a.h" includes itself: gk20a.h -> clk.h -> clk_vin.h ->
boardobjgrp.h -> gk20a.h

Fix this by removing gk20a.h header from boardobjgrp.h
and declaring necessary structures

Also remove unused header pmu_gk20a.h from boardobjgrp.h
