gpu: nvgpu: Reduce BAR1 kernel size

Browse Source 
Reduce the BAR1 size in the kernel to match the reserved size in the
DTB. This caused problems for the buddy allocator since the allocator
can sometimes allocate from higher memory before lower memory in the
managed space. This would cause the kernel to access unmapped memory.
