gpu: nvgpu: abstract away dma alloc attrs
Don't use enum dma_attr in the gk20a_gmmu_alloc_attr* functions, but
define nvgpu-internal flags for no kernel mapping, force contiguous, and
read only modes. Store the flags in the allocated struct mem_desc and
only use gk20a_gmmu_free, remove gk20a_gmmu_free_attr. This helps in OS
abstraction. Rename the notion of attr to flags.
Add implicit NVGPU_DMA_NO_KERNEL_MAPPING to all vidmem buffers
allocated via gk20a_gmmu_alloc_vid for consistency.
Fix a bug in gk20a_gmmu_alloc_map_attr that dropped the attr
parameter accidentally.
Bug 1853519
