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.

At the same time we can replace calls to clk framework with the new HAL and drop direct dependency to clk framework. gp10b ops were replaced as a whole at HAL initialization. That replaces anything set in platform probe stage, so reduce that to touch only clock gating regs.

| | | | | | | | | | | | | | | | | | | | | | | Reorganize the HW headers of gk20a. The headers are moved to a new directory: include/nvgpu/hw/gk20a And from the code are included like so: #include <nvgpu/hw/gk20a/hw_pwr_gk20a.h> This is the first step in reorganizing all of the HW headers for gm20b, gm206, etc. This is part of a larger effort to re-structure and make the driver more readable and scalable.

| | | | | | | | | | | | | | | | | | | Move the GPU allocators to common/mm/ since the allocators are common code across all GPUs. Also rename the allocator code to move away from gk20a_ prefixed structs and functions. This caused one issue with the nvgpu_alloc() and nvgpu_free() functions. There was a function for allocating either with kmalloc() or vmalloc() depending on the size of the allocation. Those have now been renamed to nvgpu_kalloc() and nvgpu_kfree().
