gpu: nvgpu: reserve wpr from allocator

In addition to nonwpr_base address, allocate also the wpr_base that is
configured as wpr, in order to not overlap user allocations on that
area.

This patch adds just the wpr region's mem_desc field available. For
devices that use the wpr separately, the field is used for that alloc.
