gpu: ion: Allocate the sg_table at creation time rather than dynamically

Browse source

Rather than calling map_dma on the allocations dynamically, this patch
switches to creating the sg_table at the time the buffer is created.
This is necessary because in future updates the sg_table will be used
for cache maintenance.
