drm/amdgpu: Support contiguous VRAM allocation
RDMA device with limited scatter-gather ability requires contiguous VRAM
buffer allocation for RDMA peer direct support.
Add a new KFD alloc memory flag and store as bo alloc flag
AMDGPU_GEM_CREATE_VRAM_CONTIGUOUS. When pin this bo to export for RDMA
peerdirect access, this will set TTM_PL_FLAG_CONTIFUOUS flag, and ask
VRAM buddy allocator to get contiguous VRAM.
