Introduce accessors for TTM buffer object memory that has been mapped into the kernel virtual address space or as IO memory. IO memory needs to be accessed via special accessor functions, not by dereferencing the iomem cookie. The wrappers hide the details of 32-bit access and honour the TTM map type. nv04_crtc_cursor_set() is changed to use the new wrappers. 'cursor' is received from

Use ioremap() for mapping the channel user regs (that are never exposed to user space) instead of drm_addmap(). This removes the last use cases of drm_addmap/drm_rmmap from Nouveau.

nouveau_bo_wait will make the GPU channel wait for fence if possible, otherwise falling back to waiting with the CPU using ttm_bo_wait.
