Deepak Nibade 577c69322e gpu: nvgpu: increase bootstrap vidmem carveout to 256M ...

We right now have a bootstrap carveout in vidmem of size 16M and having base
address at {total_vidmem_size - 256M}
So this design divides rest of the vidmem into two chunks

And the size of bootstrap carveout is also small and insufficient for vidmem
allocations during boot

Hence increase the bootstrap vidmem carevout to 256M and move it to the end
of entire vidmem

Rename the carevout name for wpr_co to bootstrap_co as it is more appropriate

Also update __nvgpu_vidmem_do_clear_all() to clear only one chunk of vidmem
instead of two
