Rename some functions to better names.

Rename some functions to better names.

devfs_find_device_by_udev() -> devfs_find_device_by_devid()
dev2udev() -> devid_from_dev()
udev2dev() -> dev_from_devid()

This fits with the rest of the code. 'dev' usually means a cdev_t,
such as in make_dev(), etc. Instead of 'udev', use 'devid', since
that's what dev_t is, a "Device ID".

drm: dev->dma_lock doesn't exist

drm: Implement and use Linux struct device

drm cleanup 19/x: Switch more calls to kzalloc/kfree helpers.

Slightly reduces differences in already complicated codes.

No functional change.

drm cleanup 06/x: Remove KIB_NOTYET macro.

Not used even at FreeBSD.

While there, remove few other from initial port.
