gpu: nvgpu: make bootstrap allocations contiguous

We use bootstrap vidmem allocator for all the vidmem allocations that happen
boot time
And we need to program physical address for all the potential vidmem buffers
that we program into h/w and are needed during boot

So force the allocator to allocate contigous memory

We otherwise see a warning dump when we program physical address of memory which
is allocated in multiple pages
