add a comment explaining DRM_NETBSD_ADDR2HANDLE/DRM_NETBSD_HANDLE2ADDR:

 * This hack strips the top bit from amd64 addresses, which avoid
 * udv_attach() returning NULL for "negative" offset.
 * A better hack would be to encode the offset of some kernel data
 * structure..

add a new DRM_HANDLE_NEEDS_MASK macro to check whether the above need to
be applied for various mapping types (_DRM_SHM and _DRM_SCATTER_GATHER.)

also:
- use IPL_VM for now
- use a lot of bus_space
- struct drm_device now has a pointer to the device_t
