gpu: nvgpu: Fix boardobj allocation size

Browse Source 
In current implementation we are allocating boardobj
in nvgpu_boardobj_construct_super for all units and assigning
that pointer to boardobj type, as the size differe for different
units assigning the boardobj pointer to a common type will
give violations. Fixing them by allocating mem a head
and later call construct_super for elements initialization.
