Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

-/**
- * struct dma_buf_ops - operations possible on struct dma_buf
- * @attach: [optional] allows different devices to 'attach' themselves to the
- *	    given buffer. It might return -EBUSY to signal that backing storage
- *	    is already allocated and incompatible with the requirements
- *	    of requesting device.
- * @detach: [optional] detach a given device from this buffer.
- * @map_dma_buf: returns list of scatter pages allocated, increases usecount
- *		 of the buffer. Requires atleast one attach to be called
- *		 before. Returned sg list should already be mapped into
- *		 _device_ address space. This call may sleep. May also return
- *		 -EINTR. Should return -EINVAL if attach hasn't been called yet.
- * @unmap_dma_buf: decreases usecount of buffer, might deallocate scatter
- *		   pages.
- * @release: release this buffer; to be called after the last dma_buf_put.
- * @begin_cpu_access: [optional] called before cpu access to invalidate cpu
- * 		      caches and allocate backing storage (if not yet done)
- * 		      respectively pin the objet into memory.
- * @end_cpu_access: [optional] called after cpu access to flush cashes.
- * @kmap_atomic: maps a page from the buffer into kernel address
- * 		 space, users may not block until the subsequent unmap call.
- * 		 This callback must not sleep.
- * @kunmap_atomic: [optional] unmaps a atomically mapped page from the buffer.
- * 		   This Callback must not sleep.
- * @kmap: maps a page from the buffer into kernel address space.
- * @kunmap: [optional] unmaps a page from the buffer.
- * @mmap: used to expose the backing storage to userspace. Note that the
- * 	  mapping needs to be coherent - if the exporter doesn't directly
- * 	  support this, it needs to fake coherency by shooting down any ptes
- * 	  when transitioning away from the cpu domain.
