Alex Waterman c71e764348 gpu: nvgpu: Remove alloc_inst_block from mm HAL
The alloc_insty_block() function in the MM HAL is not a HAL. It does
not abstract any HW accesses; instead it just wraps a dma allocation.
As such remove it from the HAL and move the single gk20a implementation
to common/mm/mm.c as nvgpu_alloc_inst_block().
